Chapter 214: Chapter 134: The Old Professor’s Casual Note

Inside the mathematics department building at Rutgers University, the air conditioning was running strong. Thick carpets lined the hallways, absorbing the footsteps of passersby and creating a profound silence.

Professor Arthur sat in his office, holding a cup of coffee that had long gone cold.

His desk was piled with several stacks of printed manuscripts of varying heights, some with their corners already curling up.

As a senior editor for *Discrete Mathematics*, he had to review a large volume of submissions every month.

The glow of the computer screen reflected off his glasses. He rubbed the corners of his sore eyes and tossed the forty-page graph theory manuscript in his hand back onto the desk.

"Another one of these uninspired, brute-force categorizations."

Arthur leaned back in his swivel chair and muttered a complaint.

To prove a lower bound for local connectivity, the author of that last paper had painstakingly listed over seventy different subgraph structures. The proof itself wasn’t wrong, but reading it felt like watching someone trim an entire golf course with a pair of nail clippers.

The office door wasn’t fully closed, leaving a small crack.

Thomas from the office next door pushed the door open and walked in, carrying a mug with the university logo on it. He was a tall, thin, middle-aged man.

"Still going through that pile of graph theory papers?"

Thomas pulled out a chair across from Arthur and sat down, casually flipping through the thick stack of papers on the desk.

"I heard you sighing all the way from the hallway. Is this quarter’s batch no good?"

"It’s not just no good, it’s too clumsy."

Arthur took a sip of his cold coffee and shook his head with a bitter smile.

"Young scholars these days seem to have fallen into a strange rut. They get a good computer and think they can solve every problem with brute-force methods. Their papers are filled with complex conditional branches, completely devoid of any mathematical beauty."

Thomas smiled without disagreeing. He reached over and picked an envelope from the unread mail tray on the corner of Arthur’s desk.

The envelope had several airmail stamps from China Post, and the postmark was dated half a month ago.

"Sent from Hua Country?"

Thomas glanced at the return address.

"Hua Country Science and Technology University. If you don’t want to look at it, you want me to open it for you?"

"Go ahead. I could use a two-minute break for my eyes anyway."

Arthur took off his glasses and slowly wiped them with a soft cloth.

Thomas casually picked up the letter opener on the desk and slit open the envelope.

There wasn’t a thick stack of paper inside.

What he pulled out was just five thin sheets of A4 paper. The layout was a very basic English document format, without so much as a header. It was clean to the point of being spartan.

"Only five pages?"

Thomas was taken aback for a moment.

In an era where graph theory papers often ran dozens of pages long, a five-page submission was extraordinarily short—so short it looked more like an unfinished research proposal.

Arthur put his glasses back on, also a bit surprised by what he heard.

"Can you even properly explain a lower bound in graph theory in five pages? What’s the title?"

"’Algebraic Reconstruction of a Lower Bound for a Specific Class of Bipartite Graphs.’"

Thomas read the bolded line at the top aloud. After he finished, his eyes moved down from the title to the main text.

The office fell silent.

Only the soft whirring of the air conditioner vent could be heard.

Thomas’s gaze lingered on the first page for about two minutes. His brow slowly furrowed, and his body, which had been casually leaning back in the chair, unconsciously leaned forward.

He didn’t turn the page. Instead, he read the first page again from top to bottom.

"Arthur." Thomas’s voice had changed, losing its earlier relaxed, conversational tone. "You have to see this."

Arthur noticed the change in his old colleague’s expression, put down his coffee cup, and held out his hand.

Thomas handed the five pages over.

Arthur took the paper and his eyes fell upon it.

The first paragraph was a very conventional introduction, outlining in a few sentences the challenges the problem currently posed to the academic community.

The language was very plain, using only the most basic English vocabulary with no fancy clauses.

As he read on, Arthur’s gaze froze.

Instead of defining various subgraph structures in the traditional way, the author had constructed an adjacency matrix right at the end of the first page.

"He took the graph’s connectivity..."

Arthur muttered, his eyes quickly scanning the second page.

The second page was filled with neatly formatted matrix derivations. Using the matrix’s characteristic polynomial, the author had unreasonably dragged a topological problem—one that would normally require hundreds of case-by-case discussions in geometric space—into a purely algebraic space.

Here, there were no complex graphical branches.

Only the distribution patterns of the eigenvalues.

Arthur began turning the pages faster and faster.

On the third page, the author introduced a very clever inequality for bounding the eigenvalues.

This bounding technique was common in the field of algebra, but applied to this specific graph theory model, it was a perfect fit—like a key sliding into a lock.

Page four, the calculation concluded.

On the fifth page, which was only half-full, was the derivation of the lower bound value that had been a headache for so many scholars.

In the bottom right corner was a small black square, signifying the end of the proof.

Not a single wasted word.

Not a single superfluous lemma.

Arthur finished reading the last symbol and placed the paper on his desk. He took off his glasses, rubbed the bridge of his nose, and then put them back on.

"He bypassed the combinatorial construction entirely."

Arthur looked at Thomas, his tone filled with delighted admiration.

"Using the spectral gap of a matrix to constrain the graph’s lower bound... people have tried this path before, but they always got stuck on bounding the boundary conditions. This person’s handling of the bounding technique is so masterful, it’s as if they take regular strolls through this field."

"A very beautiful algebraic entry point."

Thomas nodded in agreement.

"Clean, efficient. These five pages are worth more than the entire stack on your desk, that forty-page paper included."

Arthur picked up the first page, his gaze falling on the author’s name below the title.

There was just a simple name there:

C. Zhuo.

"C. Zhuo."

Arthur read the name aloud.

"A scholar from Hua Country Science and Technology University... This writing style is too polished. It’s not at all like a young researcher who needs to pad their word count to show they’ve done the work. Have you ever heard of this person?"

Thomas stared at the name as if something had just flashed through his mind. He frowned slightly and tapped his fingers on the armrest of his chair a couple of times.

"Hua Country Science and Technology University, C. Zhuo..."

Thomas murmured to himself.

"Arthur, do you ever read preprints from the physics field?"

"Not usually. I don’t really understand them. Why?"

"A few months ago, Delian from Princeton published a preprint on physical singularities. The paper caused quite a stir because Delian used a very obscure algebraic structure to bypass a deadlock related to continuity while tackling a manifold problem."

Thomas paused, looking at Arthur.

"In the acknowledgments of that paper, Delian made a point of mentioning someone. He thanked a ’C. Zhuo from Hua Country Science and Technology University’ for providing the ’decisive insight’ for the construction of the algebraic model."

Arthur was stunned.

He might not be a physicist, but he knew Delian’s standing in the academic world. A big shot of that caliber would never casually drop an irrelevant name in their acknowledgments.

"Providing an algebraic model..."

Arthur looked down again at the five pages in his hand—a complete deconstruction of a graph theory problem using algebraic matrices. A logical conclusion began to form naturally in his mind.

"So it’s him."

Arthur nodded in sudden understanding.

"That explains it. This C. Zhuo must be a senior professor at Hua Country Science and Technology University with deep expertise in both algebra and physics. This kind of seasoned, direct-to-the-point problem-solving approach definitely wasn’t forged by toiling away in graph theory. He’s looking down on the problem from a higher dimension."

"He probably picked up this lower bound problem from graph theory as a small side project while mentoring students recently."

Thomas leaned back in his chair with a smile.

"A casual piece like this is a gift for us. It saves us a lot of time we’d otherwise spend reading garbage submissions."

"Indeed."

Arthur picked up a red pen from his desk and drew a circle on the top right corner of the first page.

There was no question, no request for a supplementary, tedious combinatorial proof. In the face of such a logically self-consistent and elegantly high-dimensional manuscript, any suggestion for a major revision would seem like nitpicking.

"There’s nothing to change. It just needs a little polishing on the formatting."

Arthur placed the manuscript into the "Accepted" tray on his right.

"The upcoming autumn issue is still short one substantive short article. We’ll save the spot for him."

Thomas nodded and stood up, picking up his mug.

"Well, I’ll let you get back to it. Have fun with your brute-force categorizations. Hope you stumble upon a few more of these little gems from senior professors today."

Thomas walked out of the office, joking as he went.

Arthur looked at the thin manuscript from China on his desk, his mood significantly brightened.

He picked up the cold coffee, took a sip, and suddenly found that even the bitter brew went down a lot smoother.
