On a certain class of linear relations among the multiple zeta values arising from the theory of iterated integrals

Speaker: 
Minoru Hirose

Date:

Location: 
MPIM Lecture Hall

In this talk, we consider iterated integrals on a projective line minus generic four points and introduce a new class of linear relations among the MZVs, which we call confluent relations. We start with Goncharov’s notation for iterated integrals, review some basic notions and properties of iterated integrals, and define a class of relations among iterated integrals, which naturally arise as “solving differential equations step by step”. Confluent relations are defined as the limit of these relations when merging two out of the four punctured points.

In the 90s Crane-Frenkel proprosed the construction of a 4d TQFT from a bimonoidal category, that is, a category equipped with both a monoidal and comonoidal structure so that the data defining the comonoidal structure is itself monoidal. In this talk I will explain a conceptual reason for the connection between bialgebras and TFTs. Secondly, I will describe how to extend the classical construction of the Hall algebra of an abelian category to produce new examples of bimonoidal categories: the Hall bimonoidal categories.

 In 1975 Cohen constructed a series of modular forms of half-integral weights. Its q-coefficients contain special values of Dirichlet functions and were used by Cohen to create various equations of them with arithmetic functions. The modular forms are called Cohen-Eisenstein series and were later generalized to the case for Hilbert modular forms.

On a mean value result for a product of $L$-functions

The asymptotic behaviour of moments of $L$-functions is of special interest to number theorists and there are conjectures that predict the shape of the moments for families of $L$-functions of a given symmetry type. However, only some results for the first few moments are known. In this talk we will consider the asymptotic behaviour of the first moment of the product of a Hecke $L$-function and a symmetric square L-function. This is joint work with O. Balkanova, G. Bhowmik, D. Frolenkov.

On the structure of mixed weight Hilbert modular forms

In this talk we discuss joint work with Sho Takemori on Hilbert modular forms
over the real quadratic field of discriminant 5, with respect to its full modular group.
The graded ring of all Hilbert modular forms of parallel weight were determined by Gundlach.
By using his result and some elementary technique, we establish a structure theorem on mixed
Hilbert modular forms.

Computing weight 1 forms -- a p-adic approach

The computation of Hecke-eigenforms of weight at least 2 is readily accomplished through the
theory of modular symbols as these Hecke-eigensystems occur in the cohomology of modular
curves.  However, the same is not true for weight 1 modular forms which makes computing
the dimensions of such spaces difficult let alone the actual system of Hecke-eigenvalues. 
Recently effective methods for computing such spaces have been introduced building on an
algorithm of Kevin Buzzard.  In this talk, we present a different, p-adic approach towards

A p-adic family of Saito-Kurokawa lifts for a Coleman family and the Bloch-Kato conjecture

Kenji Makiyama

Location: 
MPIM Lecture Hall

We will construct a $p$-adic family of Saito-Kurokawa lifts for a Coleman family and extend the result of Agarwal and Brown on the Bloch-Kato conjecture for elliptic modular forms of low weights to higher weights. More precisely, we will prove that the $p$-valuation of the order of the Selmer group of a Coleman deformation is bounded below by the $p$-valuation of the algebraic part of the critical $L$-value attached to the initial Hecke eigenform of a Coleman family satisfying some reasonable assumptions given by Agarwal and Brown.

Friedrich Hirzebruch Lecture

Posted in
Location: 
University Club Bonn

The annual Friedrich Hirzebruch Lecture is a series of lectures started in 2007 on the occasion of the 80th birthday of Prof. Friedrich Hirzebruch. The lectures address a general audience and aim at illustrating the relation between mathematics and art, society and other fields.

C. Kaiser
Date: 
Thu, 2013-01-31 15:00 - Thu, 2026-12-31 16:00
Location: 
MPIM Lecture Hall

The Oberseminar is a very long running seminar at MPI (‘Ober‘ standing for 'upper'). Its idea is that the guests of the MPI speak in this seminar (hopefully early in their stay) and get the chance to explain their work to the other guests.
