In mathematics, Khabibullin's conjecture, named after , is related to Paley's problem for plurisubharmonic functions and to various extremal problems in the theory of entire functions of several variables. (Wikipedia).
In this video, I state and prove Chebyshev's inequality, and its cousin Markov's inequality. Those inequalities tell us how big an integrable function can really be. Enjoy!

Introduction to Differential Inequalities
What is a differential inequality and how are they useful? Inequalities are a very practical part of mathematics: They give us an idea of the size of things -- an estimate. They can give us a location for things. It is usually far easier to satisfy assumptions involving inequalities t

Introduction to additive combinatorics lecture 2.7 --- Khovanskii's theorem
Khovanskii's theorem states that if A is a finite subset of an Abelian group and nA = A+A+...+A, where there are n A's in the sum, then the size of nA is a polynomial function of n when n is sufficiently large. The proof given here is due to Melvyn Nathanson and Imre Ruzsa. 0:00 Introduct

Bo’az Klartag: On Yuansi Chen’s work on the KLS conjecture II
The Kannan-Lovasz-Simonovits (KLS) conjecture is concerned with the isoperimetric problem in high-dimensional convex bodies. The problem asks for the optimal way to partition a convex body into two pieces of equal volume so as to minimize their interface. The conjecture suggests that up to

Introduction to additive combinatorics lecture 1.8 --- Plünnecke's theorem
In this video I present a proof of Plünnecke's theorem due to George Petridis, which also uses some arguments of Imre Ruzsa. Plünnecke's theorem is a very useful tool in additive combinatorics, which implies that if A is a set of integers such that |A+A| is at most C|A|, then for any pair

Galyna Livshyts: On some tight convexity inequalities for symmetric convex sets
We conjecture an inequality which strengthens the Ehrhard inequality for symmetric convex sets, in the case of the standard Gaussian measure. We explain its relation to other questions, such as the isoperimetric problem, and (if time permits), to the tight bound in a version of the Dirichl
