The entire subject of combinatorics.

[Anonymous No.11470543]

>>11468252
Rudin isn’t bad. There are at most 2-3 sentences of the obvious omitted from the proofs, but I don’t think he’s a great read the first time around personally, and that has more to do with the way he presents analysis (no pictures, all formalism), which paints the subject as drier than it actually is unless you already appreciate it
This is usually rectified by the professors in class, but as far as a self studying text, try and find lectures that match the book with pictures.

Honestly any math subject can be a range from simple to brainlet filter to actually open problem difficulty given how it's taught. Imagine a class where the teacher prints out every provable theorem in Euclid or any other textbook and you prove them all.

Literally read Diestel's or Bollobas's graph theory, some texts in number theory, and do lovasz's combinatorial problems and exercises. This is the basic math primer for popular algorithms and the mathematics they use. Knuth's concrete math is good, but in general I really don't think AoCP is worth reading seeing as how it's more a mark of the knowledge of a decade past rather than a proper book to read out of

To get into les grands écoles, you have to at least be Olympiad level , you have to Master Galois theory ,abstract algebra, Topology , French literature and Philosphy in just two years just to have crack at getting accepted into l'X , and all this is just as an engineer , you're not even a mathematician.

Not only that but the exercices you get are not the stupid shit you get in anglo universities ,where if you take a course on complex numbers , on the test day they'll give you stupid stuff like what's the conjugate of " a + bi " and add in multiple choices to help you and after you're done with the course you forget everything you learned.

In prépa every question you get is gonna be some sort of probléme where you have to use all different sorts of mathematical knowledge to solve , and to add that you have to do a test every single week on everything that you studied up to that point.
If you're not at least AIME II level and have very strong mental fortitude you have no business being in prépa.

X students are engineers in name only. They are taught extremely advanced physics and maths just for the sake of it. Some of them even do QFT just because they can and because they could be tempted to do research after their 4 years of military service.

(most X students don't actually serve in the Army, they get "head-hunted" and the company which hires them pays back the costs of "deserting".)

>>11471497
>>11471520
Maybe it was true 20 years or so ago. Prépa's programme has been slightly watered down and most of the "encyclopedism" the prépa were known for happens at the Graduate level if they are accepted in ENS, X, or other high-level grandes écoles.

Prépas nowadays mostly give you a very solid and very throughout mathematics and physics background corresponding to a good undergrad's knowledge. Emphasis is put on developing techniques to quickly read and adapt to different problems, context, and notions, even ones you couldn't study in prépa for the lack of time. You don't need to digest an incredibly abstract and huge amount of material to do that.

One of the most egregious examples of that was a prépa analysis textbook which developed extremely powerful and intricate properties of integrals and estimates without once using Lebesgue theory or calculus of residues.

To give names, the biggest "named theorems" you will see in a prépa are on the level of Cayley-Hamilton, Cauchy's integral theorem, D'Alembert-Gauss (fundamental theorem of Algebra), you may also venture into group actions and shit like that.

This is even more impressive in physics. The curriculum is more or less designed to squeeze the most of Newton's formalism without ever mentioning, Lagrangians, Hamilltonians, or the general theorem of ODE which helps to put these things into context.

"normal" engineering schools will use this material as a basis. X and ENS will however give you things you never learnt before in the intro and ask questions about it to test your adaptability.

You forgot to mention some important stuff , like in prépa there are expectations of you , you are supposed to have some general knowledge outside of math and physics.
You'll get a general knowledge test and they'll ask you about advanced vocabulary and questions like who is Rey charles and who's the president of Syria.

>Prépas nowadays mostly give you a very solid and very throughout mathematics and physics background corresponding to a good undergrad's knowledge.
Yes , while this is true , the main difference is that you're expected to accumulate all tat knowledge in 2 years instead of 4 and you're supposed to remember most of it.
> X and ENS will however give you things you never learnt before in the intro and ask questions about it to test your adaptability.
This , the exercises are grueling , you are expected to have a good amount of critical thinking , and to be adaptable.
In the west a good student is expected to get an A meaning he understood 90% of the material.
In France an excellent student will get 15/20 like 75% , and this i think illustrates the difference.

Also while a lot of advance stuff isn't mandated officially , a good prépa student will go above and beyond to seriously be able to compete.
Some good prépa schools recommend you read Nikolas bourbaki >>11471139

>you are supposed to have some general knowledge outside of math and physics.
this is a pseudo-specificity of the French education system (which may disappear with Bl*nquer sadly)
"Scientific" High-Schoolers have philosophy and History as an elective, "Literary" High-Schoolers have an option to continue Maths (focusing on the social aspects and the epistemology).

Even I, from a "lowly" (ie, not recognized outside of its very specific field of Optics and Nanotechs) engineering grande école, had courses in various topics from Economics to Philosophy and History offered as electives.

>In France an excellent student will get 15/20 like 75% , and this i think illustrates the difference.
True, getting a 8 or 9 at the agrégation or ENS test is enough to be very proud.

>reading Bourbaki
Bourbaki is a meme and a very bad one. I wouldn't recommend it to anyone unless as a curiosity if you are extremely familiar with the material and want a different, unique outlook.

My first "really hard" math book was a textbook from 1970's recommended to prépas at the time, "Traité de Maths supérieures", by Rammis. It's actually popular and pedagogical enough to be constantly re-edited 50 years later.
Reading Rammis gave me the familiarity and courage to attack more advanced books. But starting with Bourbaki is a mistake.
