[Kazım Büyükboduk]

Dear All,

IMBM (Bogazici University, Istanbul) will host our workshop on "Iwasawa
theory and (p-adic) Beilinson conjectures" to take place on September 15th
(Tuesday) and September 17th (Thursday). Please find the program of the
talks and the abstracts at the bottom of this e-mail message, as well as
the official poster.

We express our deep gratitude to IMBM for generously hosting the two
speakers (Masataka Chida visiting from Tohoku and Fabien Trihan from
Tokyo). The talks will take place in the IMBM building (located in the
Bogazici University South Campus). We welcome all interested audience!

ABSTRACTS

Exceptional zeros of p-non-ordinary forms and Perrin-Riou's conjecture
(Buyukboduk):

I will report on a joint work with Denis Benois where we prove a p-adic
Beilinson formula for the second derivative of the p-adic L-function
associated to a newform f which is non-crystalline semistable at p, at its
central critical point, by expressing this quantity in terms of a p-adic
(cyclotomic) regulator defined on an extended trianguline Selmer group. We
also prove a two-variable version of this result for height pairings we
construct by considering infinitesimal deformations afforded by a Coleman
family passing through f. This, among other things, leads us to a proof of
a version of Perrin-Riou's conjecture in this set up, allowing us to relate
Heegner cycles on appropriately chosen Shimura curves to Beilinson-Kato
elements.


Selmer groups and the central values of L-functions for modular forms
(Chida):

In this talk, we will discuss on a relation between the order of Selmer
groups and the central values of Rankin-Selberg L-functions associated to
modular forms and finite order Hecke characters. In particular, we will
show that the non-vanishing of the central L-value implies the finiteness
of Selmer groups under mild assumptions, which is expected by Bloch-Kato's
Tamagawa number conjecture. This is a generalization of results by
Bertolini-Darmon and Longo-Vigni to higher weight modular forms. The proof
uses a Kolyvagin system constructed from CM cycles on Kuga-Sato varieties
over Shimura curves.


Beilinson-Flach elements for higher weight modular forms (Chida):

This is a joint work with François Brunault. In this talk, we will
construct an element in higher K-groups of the product of two Kuga-Sato
varieties. This gives a generalization of Beilinson-Flach elements to
higher weight modular forms. Also we will introduce an explicit formula for
the image of the element under the regulator map. This result is related to
Beilinson's conjecture on non-critical values of Rankin-Selberg L-functions
for modular forms.


Geometric Iwasawa Main and Equivariant Tamagawa Number Conjectures (Trihan):

Let A/K be an abelian variety over a function field of characteristic p>0.
We will give a survey on recent results concerning the Iwasawa Main and ETN
conjectures in this context.
