Chapter 382

Five minutes later, Classmate Chali ran back panting.

"God, you can use the borrowing card of my classmate who I borrowed first." Chali gasped and handed a borrowing card to Cheng Nuo.

Cheng Nuo took it and said with a smile, "Thank you."

"No, no thanks." Chali waved his hand quickly, scratched his head, and said to Cheng Nuo with a smile, "God, let's go in together."

"Walk!"

The two of them went in smoothly, first found an empty table and put down their schoolbags, and then under the guidance of Chali, they walked towards the mathematics section of the library.

There are ten rows of bookshelves, all of which are densely packed with books related to mathematics subjects, and there are at least tens of thousands of books.

The scope covered includes almost all kinds of books from easy to difficult in the field of mathematics.

Standing in front of the bookshelf, Cheng Nuo was fascinated.

This...is simply a paradise on earth!

I suppressed my excitement, took a deep breath, and searched for the books he needed step by step.

In three or four days, he will return to the office and overcome new projects with Professor Fresnel.

As for that new project, Cheng Nuo guessed that 80% of it should still be a topic in the field of geometry.

Among all the branches of mathematics, geometry is not Cheng Nuo's best at. Of course, as for Cheng Nuo's ability in geometry, it is naturally more than enough to be Professor Fresnel's assistant.

But Cheng Nuo's goal was not so narrow.

Taking advantage of the time, recharge more is what Cheng Nuo needs to do.

Modern European Geometry

"Affine Differential Geometry"

Ackerman Turns to Geometry

…………

Cheng Nuo quickly turned on the harvesting mode and saw the book he was interested in, and pulled it out of the bookshelf directly.

He didn't expect to be fat in one breath. When he saw that the books in his hand had been piled up, he stopped harvesting.

On the way back to the desk, Cheng Nuo happened to be in the collection of books in the number theory area. After a glance, he was suddenly attracted by the name of a book: "The Development and Recent Situation of ABC Conjecture".

I happened to listen to a lecture on ABC conjecture yesterday, so when I saw this name, Cheng Nuo subconsciously pulled out the book and put it into his "book pile".

So when Chali came back with two books, the scene he saw was Cheng Nuo holding a stack of books more than half a meter high and was gnawing.

While chewing, his face also showed an intoxicating expression.

Classmate Chali wiped a handful of sweat that did not exist on his forehead and muttered in his heart, "The great god is the great god, and even the way of reading books in the library is so unique!"

After thinking about it, he sat opposite Cheng Nuo, picked up the book and started reading it.

Even in English, Cheng Nuo reads at all not slower than usual.

A book worth more than 100 pages can only last half an hour under Cheng Nuo.

As time goes by, Cheng Nuo's geometry skills are constantly soaring.

Geometry is one of the oldest among all the branches of mathematics. From the period of the four ancient civilizations to the present, it may have a history of more than 3,000 years.

Thousands of years of accumulation and development have made geometry a very advanced subject.

Even Professor Fresnel, who is at the top of the world's mathematics community, may not dare to say that he can study this subject thoroughly, let alone Cheng Nuo now.

He is like a sponge in the vast ocean, absorbing the water of knowledge as much as possible.

Mathematics makes people happy. This sentence is indeed true.

When you are sad, take out a math book and study it carefully, and it will make people forget their sorrow.

When you are happy, you have to take out a math book and savor it slowly, and you will definitely be happier!

Cheng Nuo was in such a state. He was in a good mood and felt even more happy after reading three or four books on geometry.

Chali, who was opposite, looked up from time to time to observe Cheng Nuo's expression while reading a book.

Seeing Cheng Nuo's ever-increasing corners of his mouth, Classmate Chali couldn't help but feel even more confused.

After a while, Cheng Nuo was a little tired of reading books on geometry, so he took the thin book "The Development and Recent Situation of ABC Conjecture" in front of him.

The name of the abc conjecture was well known before, but it has never carefully studied its difficulty.

But it is generally recognized that in addition to the six of the seven major conjectures of the millennium that have not been resolved, the ABC conjecture can rank in the second echelon.

Even compared to the Goldbach conjecture, the difficulty alone is higher than that.

Now, Cheng Nuo wants to really experience it.

After turning on the first page, Cheng Nuo roughly browsed the directory.

Sure enough, all the books about the ABC conjecture, Ueda Shinichi is an obstacle that cannot be overcome. About one-third of this book is related to Ueda Shinichi.

Compared with famous members of the mathematical conjecture family, such as the Riemann Conjecture, the Goldbach Conjecture, the twin prime number conjecture, and (proven) the former Fermat Conjecture, the "qualification" of the ABC Conjecture is very shallow, because the other conjectures are all "old seniors" over the age of 100.

This conjecture was proposed in 1985 and was not well-known at that time, but it was only after later generations noticed the importance of this conjecture that they entered the vision of world mathematicians.

In fact, the content of the ABC conjecture is the same as the Goldbach conjecture, and it is not difficult for ordinary people to understand:

The abc conjecture is aimed at a positive integer array (a,b,c) that meets two simple conditions. The first condition is the mutual element of a and b, and the second condition is a+b=c.

Obviously, there are infinitely many positive integer arrays that meet this condition, such as (3, 8, 11), (16, 17, 33). In order to elicit the abc conjecture, take (3, 8, 11) as an example, to do a simple calculation of "three steps":

1Multiple a, b, c (the result is 3x8x11=264);

2 Perform prime decomposition of the product (the result is 264=23x3x11);

3Multiple all the different prime numbers in the prime decomposition (the result is 2x3x11=66).

Now, compare the larger of the three numbers a, b, and c (i.e. c) with the result of step 3, and you will find that the latter is greater than the former. If you look for some other examples, you may also find the same result.

But this is not a rule. There are countless counterexamples, such as (3, 125, 128), etc., but if the result of 3 is added to a power greater than 1, the number of counterexamples will become finite from infinite.

Simply put, the abc conjecture is a conjecture that allows for the existence of counterexamples.

Therefore, the method of using supercomputers to find counterexamples to prove conjectures is simply not applicable to this problem.

After reading the question, Cheng Nuo took out a piece of draft paper and wrote and painted for a while.

Half an hour later, I could only sigh dejectedly, "It's so difficult!"

Sure enough, this kind of world-class guess cannot be used by any charming product.

This guess is really informative!

No clue, no clue.

Cheng Nuo did not read the later analysis of several mathematical masters in the book about this conjecture. He tried it alone, but found that he had a defeat on the whole line.

He could not find any breakthrough to overcome this conjecture.
