DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/ceros
 refinadosypadicos/2/">Exceptional zeros\, modular forms of weight 1 and Eu
 ler Systems</a>\nby Oscar Rivero (UPC\, Barcelona) as part of Ceros excepc
 ionales refinados y p-adicos\n\n\nAbstract\nA large number of works illust
 rate how the phenomenon of exceptional zeros allows to obtain relevant res
 ults in the study of the arithmetic of Galois representations. Some exampl
 es go through the p-adic Birch and Swinnerton-Dyer conjecture or Gross-Sta
 rk conjectures\, which we will recall in the first part of the talk. Next\
 , we will focus on a case that has elements in common with the other two c
 ontexts\, which is that of the adjoint of a weight one modular form. We wi
 ll discuss two strategies to approach to the proof of a formula of the spe
 cial values ​​for the  p-adic L-function of the adjoint and that invol
 ves units and p-units in numbers fields. The first approach uses Greenberg
 -Stevens formalism and Galois deformation theory\, while the second will s
 erve to emphasize the connection with Euler systems\, where we can observe
  phenomena of exceptional zeros that reproduce the same L-invariants.\n

 s and Darmon points</a>\nby Santiago Molina (UPC\, Barcelona) as part of C
 eros excepcionales refinados y p-adicos\n\n\nAbstract\nI will explain the 
 construction of anticyclotomic p-adic L-functions associated with quadrati
 c extensions. In addition\, I will show some results on exceptional zeros\
 , with a special focus on an ongoing work joint with Víctor Hernández wh
 ere we study exceptional zero formulas related to Darmon points.\n

 Concordia University) as part of Ceros excepcionales refinados y p-adicos\
 n\n\nAbstract\nAfter recalling the conjectures of Deligne and Coates-Perri
 n-Riou on special values of L-functions and their p-adic interpolation\, w
 e shall concentrate on the case the L-functions associated with Siegel mod
 ular\, in particular the Spin L-function for GSp6. This is joint work with
  E. Eischen and S. Shah\n

 a>\nby Yiwen Ding (BICMR\, Peking University) as part of Ceros excepcional
 es refinados y p-adicos\n\n\nAbstract\nIn this talk\, I will discuss a (pr
 evious) joint work with Christophe Breuil on L-invariants. I will first di
 scuss how to see the Fontaine-Mazur L-invariants (of special p-adic Galois
  representations) in certain appropriate Galois deformations. Then I will 
 focus on the 3-dimensioal case\, and explain how to find the explicit info
 rmation of L-invariants in p-adic representations of GL3(Qp). Finally\, I 
 will discuss some results on the local-global compatibility on L-invariant
 s\, proved using "GL2(Qp)-ordinary families"\n
