Lin Chuan stared at the book in his hand, his feelings very complicated.

The book is titled "Some Thoughts on the Weakened Version of the Bech and Swinnetton-Dale Conjectures," and is written by Phineas Barkley.

This is definitely a great product!

The hard work of shuttling between the two worlds for many days, getting up early and working late, seems to finally be showing some results.

The book was written in English. Lin Chuan's English is quite good; he's even published papers, so understanding the content shouldn't be a problem for him.

The Birch and Swinnerton-Dyer conjecture, often abbreviated as BSD conjecture, is one of the seven great conjectures in mathematics.

And this mathematician named Phineas Buckley is studying it.

Open the table of contents.

The first part, the introduction, outlines the history, significance, and known results of the Bech and Swinnetton-Dyer conjecture.

The second part, Preliminary Knowledge, introduces basic concepts such as elliptic curves, L-functions, rank, and Tat-Salevich groups.

Then comes a detailed analysis of the existing weak conjectures, including the Kolyvagin-Flach theorem, the Gross-Zajil formula, and the modularity theorem.

Lin Chuan even saw a Chinese name here.

Zhang Wei.

The book states that he discovered and proved the higher-order GGP conjecture, which was a groundbreaking step toward proving the BSD conjecture for the case of rank ≥ 2.

Lin Chuan was puzzled when he saw this.

The writing system in this world, and even the names of some mathematicians, are exactly the same as those in the real world.

This overturned many of the things Lin Chuan had originally envisioned.

Could it be that the wasteland world is some kind of future evolution of the real world?

Why does time flow differently in the two realms?

"Forget it, now's not the time to dwell on these things."

While reading in the wasteland world these days, he also took the opportunity to read a lot about the history of mathematics.

In the real world, Zhang Wei is studying the Kudara conjecture, but he hasn't touched on the higher-order GGP conjecture, let alone proven it.

Lin Chuan knew he was about to become rich.

Unlike other post-apocalyptic novels that depict bringing gold back to the real world to make a fortune, this story brings the process of proving this advanced GGP conjecture back to the real world.

Although the higher-order GGP conjecture is a weak conjecture of the BSD conjecture, it still has very strong academic value.

After calming himself down, Lin Chuan began to look through the proof process in the book.

From the perspective of author Phineas Barkley, Zhang Wei has already proven this conjecture, so his writing is very simple.

"can't read……"

"I really don't understand."

Phineas Barkley, a mathematician Lin Chuan didn't know, was quite advanced. Even with Lin Chuan activating his "Scientific Intuition" skill, he still couldn't understand the simplified proof of the higher-order GGP conjecture.

"Looks like I need to read more books."

"I need to improve my math skills by at least a few levels."

"It will take a considerable amount of time to fully understand this proof process."

Lin Chuan pondered how to present the proof of this conjecture.

While improving his math skills, he also needs to improve his own skill level.

At the very least, one should be someone who completely outshines everyone else in the Qiushi Class or the entire School of Mathematics.

Having made up his mind, Lin Chuan scrolled down again.

The discovery of Phineas Barkley also left him with a pleasant surprise.

"Since the BSD conjecture was proposed, mathematicians have gradually overcome its weakened form by imposing various constraints."

"But a complete proof of the BSD conjecture remains a long way off."

"This chapter aims to propose a new weak BSD conjecture and prove that the BSD conjecture holds for a special class of elliptic curves under stronger but natural conditions."

"These conditions include: the existence of a second-order torsion point, the existence of an optimal modulus elliptic curve, and the existence of a globally minimal Wey model..."

Although he still couldn't understand it, Lin Chuan was even more certain that he had posted it.

If he makes sufficient preparations, he can come up with two weak BSD conjectures one after the other.

Which of these two articles could possibly be published in one of the four top mathematics journals?

"The most urgent task is to improve my math skills as quickly as possible so that I can understand and apply these two weak conjectures."

"At the same time, you need to establish a reputation in the mathematics community so that publishing papers doesn't seem out of place."

"Looks like I'll be spending all my time grinding experience between the two worlds again."

With that thought in mind, Lin Chuan solemnly closed the book and turned to look at the small note beside him.

The note had neat handwriting and described information about the area around Chenxi Garden.

Besides the information Lin Chuan already knew from his solo exploration, the note said that after passing the bus station to the south, about 20 kilometers south, there was an abandoned city called Kashiwagi City.

Although the city has been ravaged by war, Kashiwa University in Kashiwa City may still contain books that interest him.

Upon seeing this, Lin Chuan was overjoyed, but then he noticed the warning Tao Luo had left him: the city center is extremely dangerous.

Are cities more dangerous than the suburbs...?

"Or is it because the city has a high level of radiation?"

Or perhaps there are powerful alien species there?

Lin Chuan was unsure, but he listened to advice. Tao Luo had said that the abandoned city was dangerous, and he wouldn't explore it without being fully prepared.

Lin Chuan turned his attention back to the intelligence report, and the second piece of information pleased him even more than the first.

The newspaper said that if you walk about five kilometers past the western park, there is an abandoned pre-war shelter called Shelter 152.

"refuge……"

"If it's suitable, we can establish a second anchor point there."

This will provide better protection for learning environments in the wasteland.

"It's worth seeing."

After some thought, Lin Chuan made a plan to explore the wasteland world.

……

Adhering to the principle of not wasting time, Lin Chuan completed the last hour of his study session in the wasteland world.

[Your hard work has earned you +1 math experience]

Mathematics: Level 3 (400/800)

[Reward: Improved efficiency in learning fundamental mathematics]

[Reward: Improved basic mathematical understanding]

[Reward: 400 Learning Coins]

[Reward: Increases carrying capacity by 5kg when traversing the wasteland world]

[Reward: Daily travel time increased by 1 hour]

[Reward: Anchor point opening limit increased by 1]

[Enhancement: Crossing Between Worlds]

Math has been upgraded!

The learning coin reward has been doubled.

"The carrying capacity for traversing the wasteland has been increased to 20kg, but unfortunately, it's still impossible to bring anything from the wasteland back to the real world."

"The travel time can be increased to 3 hours in the real world, corresponding to 12 hours in the wasteland world..."

"The anchor point cap has been increased to 3, but unlocking the third anchor point requires a whopping 1000 learning coins! It's practically robbing us of our coins!"

After reviewing his gains from the math upgrade, Lin Chuan focused his attention on the skill: Interdimensional Travel.

The skill has actually been enhanced.

[Interdimensional Travel: You can spend 10 learning coins to enhance the travel effect near the anchor point]

Gone.

That's it?

The system didn't offer much explanation, but Lin Chuan noticed that a few small golden characters had appeared where he had originally activated the interdimensional travel: Bullet Time.

Looking at the name of this skill derived from crossing between two worlds, Lin Chuan seemed to be deep in thought.

Without hesitation, he spent 10 learning coins to activate the skill directly.

In an instant, he seemed to enter a state of stillness, unable to move an inch.

"wrong!"

"It's not that I can't move, it's that the whole world has stopped."
