 a>\nby Spencer Leslie (Duke) as part of HUJI-BGU AG-NT seminar\n\n\nAbstra
 ct\nMotivated by the study of certain cycles in locally symmetric spaces a
 nd related periods of automorphic forms on unitary groups\, I propose a th
 eory of endoscopy for certain symmetric spaces. The main result is the fun
 damental lemma for the unit function. After explaining where the fundament
 al lemma fits into this broader picture\, I will describe its proof.\n

  Gao (CNRS) as part of HUJI-BGU AG-NT seminar\n\n\nAbstract\nMazur conject
 ured\, after Faltings's proof of the Mordell conjecture\, that the number 
 of rational points on a curve depends only on the genus\, the degree of th
 e number field and the Mordell-Weil rank. This conjecture was established 
 in a few cases. In this talk I will explain how to prove this conjecture a
 nd some of its generalization. I will focus on how functional transcendenc
 e and unlikely intersections on mixed Shimura varieties are applied. This 
 is joint work with Vesselin Dimitrov and Philipp Habegger.\n

 guAGNT/3/">The motivic Satake equivalence</a>\nby Timo Richarz (Darmstadt)
  as part of HUJI-BGU AG-NT seminar\n\n\nAbstract\nThe geometric Satake equ
 ivalence is by now an indispensable tool in the Langlands program. Several
  versions of this equivalence for different cohomology theories are known\
 , such as Betti cohomology\, D-modules and étale cohomology. In this talk
 \, I explain how to apply recent advances in the theory of motives to the 
 construction of a motivic Satake equivalence. One recovers the aforementio
 ned geometric Satake equivalences under suitable realization functors. Thi
 s is joint work with Jakob Scholbach from Münster.\n

 n characteristic p</a>\nby Zev Rosengarten (HUJI) as part of HUJI-BGU AG-N
 T seminar\n\n\nAbstract\nThe Brauer group of a field\, and more generally 
 a scheme\, is a fundamental object of study in arithmetic and algebraic ge
 ometry. There is a beautiful idea\, which over fields goes back (I believe
 ) to Kato\, for understanding the p-primary part of this group in characte
 ristic p in terms of differential forms. I will present this method in det
 ail\, and discuss several important applications\, in particular to cohomo
 logy of algebraic groups and to the study of Picard groups of unipotent gr
 oups.\n

 n Pazuki (Copenhagen) as part of HUJI-BGU AG-NT seminar\n\n\nAbstract\nIn 
 the general study of regulators\, we present three inequalities. We first 
 bound from below the regulators of number fields\, following previous work
 s of Silverman and Friedman. We then bound from below the regulators of Mo
 rdell-Weil groups of abelian varieties defined over a number field\, assum
 ing a conjecture of Lang and Silverman. Finally we explain how to prove an
  unconditional statement for elliptic curves of rank at least 4. This thir
 d inequality is joint work with Pascal Autissier and Marc Hindry. We give 
 some corollaries about the Northcott property and about a counting problem
  for rational points on elliptic curves.\n

  my talk\, which reports on joint work with Ben Kane\, I  investigate vari
 ous new relations between representations of integer by quadratic forms (w
 ith congruence conditions). This is in the spirit of work of Petersson. Th
 ere is an application to 7-core partitions.\n

 lfes-Neumann (Paderborn) as part of HUJI-BGU AG-NT seminar\n\n\nAbstract\n
 In this talk we first introduce modular forms and an arithmetically partic
 ularly interesting generalization: harmonic weak Maass forms. We show how 
 these forms can be related to elliptic curves. Special harmonic Maass form
 s encode the vanishing of the central L-value and L-derivative which occur
  in the Birch and Swinnerton-Dyer Conjecture. (This is in parts joint work
  with Michael Griffin\, Ken Ono and Larry Rolen building upon work of Jan 
 Bruinier an Ken Ono.)\n
