DESCRIPTION:Title: Exceptional zeros\, modular forms of weight 1 and Euler Sys
tems\nby Oscar Rivero (UPC\, Barcelona) as part of Ceros excepcionales
refinados y p-adicos\n\n\nAbstract\nA large number of works illustrate ho
w the phenomenon of exceptional zeros allows to obtain relevant results in
the study of the arithmetic of Galois representations. Some examples go t
hrough the p-adic Birch and Swinnerton-Dyer conjecture or Gross-Stark conj
ectures\, which we will recall in the first part of the talk. Next\, we wi
ll focus on a case that has elements in common with the other two contexts
\, which is that of the adjoint of a weight one modular form. We will disc
uss two strategies to approach to the proof of a formula of the special va
lues for the p-adic L-function of the adjoint and that involves uni
ts and p-units in numbers fields. The first approach uses Greenberg-Steven
s formalism and Galois deformation theory\, while the second will serve to
emphasize the connection with Euler systems\, where we can observe phenom
ena of exceptional zeros that reproduce the same L-invariants.\n

DESCRIPTION:Title: Anticyclotomic p-adic L-functions\, exceptional zeros and D
armon points\nby Santiago Molina (UPC\, Barcelona) as part of Ceros ex
cepcionales refinados y p-adicos\n\n\nAbstract\nI will explain the constru
ction of anticyclotomic p-adic L-functions associated with quadratic exten
sions. In addition\, I will show some results on exceptional zeros\, with
a special focus on an ongoing work joint with Víctor Hernández where we
study exceptional zero formulas related to Darmon points.\n

DESCRIPTION:Title: p-adic L-functions for GSp6\nby Giovanni Rosso (Concord
ia University) as part of Ceros excepcionales refinados y p-adicos\n\n\nAb
stract\nAfter recalling the conjectures of Deligne and Coates-Perrin-Riou
on special values of L-functions and their p-adic interpolation\, we shall
concentrate on the case the L-functions associated with Siegel modular\,
in particular the Spin L-function for GSp6. This is joint work with E. Eis
chen and S. Shah\n

DESCRIPTION:Title: Higher L-invariants and local-global compatibility\nby
Yiwen Ding (BICMR\, Peking University) as part of Ceros excepcionales refi
nados y p-adicos\n\n\nAbstract\nIn this talk\, I will discuss a (previous)
joint work with Christophe Breuil on L-invariants. I will first discuss h
ow to see the Fontaine-Mazur L-invariants (of special p-adic Galois repres
entations) in certain appropriate Galois deformations. Then I will focus o
n the 3-dimensioal case\, and explain how to find the explicit information
of L-invariants in p-adic representations of GL3(Qp). Finally\, I will di
scuss some results on the local-global compatibility on L-invariants\, pro
ved using "GL2(Qp)-ordinary families"\n
