Abstract:
The Chabauty method is a remarkable tool which employs p-adic analitic methods (in particular Colman integration.) To study rational points on curves. However the method can be applied only when the genus of the curve in question is larger than its Mordell-Weil rank. Kim developed a sophisticated "nonableian" generalisation.
We shall present the classical methid, and give an approachable introduction to Kim's method.
I'm basically going to follow http://math.mit.edu/nt/old/stage_s18.html
Abstract: I will discuss applications of algebraic results to combinatorics, focusing in particular on Lefschetz theorem, Decomposition theorem and Hodge Riemann relations. Secondly, I will discuss proving these results combinatorially, using a technique by McMullen and extended by de Cataldo and Migliorini. Finally, I will discuss Lefschetz type theorems beyond positivity.
Recommended prerequisites: basic commutative algebra

The goal of my talk will be to formulate local and global Langlands conjectures
Key words: smooth representations of p-adic groups, supercuspidal representations,
automorphic representations, cusp forms, Galois representations.
The goal of my talk will be to introduce the local and the global
the Class field theory. Though definitions of all basic objects
(inverse limits, p-adic numbers, adeles, ideles, etc.) will be briefly recalled,
it is recommended that the participants review these notions
before the lecture.
The talk will be independent of the first lecture
The main goal of my talk will be to introduce adeles and ideles and to formulate the global class
field theory both for number fields and function fields.
Key words: adeles, ideles, class field theory, algebraic curves.
Abstract: A meet-tree is a partial order such that the set of vertices below any vertex is linearly ordered, and for every pair of vertices there is a greatest element smaller than or equal to each of them. I'll talk on a work in progress with Itay Kaplan and Tomasz Rzepecki mainly showing that the universal homogeneous countable meet-tree admits generic automorphisms.
Abstract: Modular forms are historically the first example of automorphic
forms, and are still studied today as they have many applications. In
this talk I want to introduce modular forms, give some examples, and, if
time permits, explain the connection to elliptic curves, objects we
already met in the first lecture.
Title: An improved bound for Hadwiger’s covering problem via thin shell inequalities for the convolution square.
Abstract: A long-standing open problem, known as Hadwiger’s covering problem, asks what is the smallest natural number N(n) such that every convex body in {\mathbb R}^n can be covered by a union of the interiors of at most N(n) of its translates. Despite continuous efforts, the best-known general upper bound for this number remain as it was more than half a decade ago, and is of the order of \binom{2n}{n}n\ln n.
Speaker: Ehud de Shalit Title:Periods and Hodge theory, complex and p-adic P-adic theory p-adic Hodge theory started with Tate in the 1960's, and witnessed two periods of great expansion: one by Fontaine and his school, the other one more recently, by Scholze and his collaborators. It has found spectacular applications in arithmetic algebraic geometry. Scholze got the Fields medal last August for this work. By analogy with the first lecture we shall try to explain the main ideas, without going into details
