DESCRIPTION:Title: Red
uctions of certain semi-stable Galois representations\nby John Bergdal
l (Bryn Mawr) as part of Boston University Number Theory Seminar\n\n\nAbst
ract\nThe L-invariant is an important p-adic invariant attached to certain
newforms of level Np where N is co-prime to p. They arise most clearly fr
om the study of local p-adic Galois representations\, but they influence g
lobal phenomena such as trivial zeros of p-adic L-functions and p-adic fam
ilies. This talk will focus on how the L-invariant\, which we will describ
e\, influences the local Galois representation modulo p. History of the ge
neral problem of calculating reductions will be provided. The main result
is an exact description of the local mod p representation when the L-invar
iant is sufficiently large in norm. One novel feature of our work is that
it allows for unbounded weights\, whereas prior descriptions were limited
to weight at most p. This is joint work with Brandon Levin and Tong Liu.\n

ecture held in MCS B31.\n\nAbstract\nWe investigate explicitly a family of
hyperelliptic curves of genus four whose Jacobians have definite quaterni
onic multiplication. This family has many interesting features\, including
: they give infinitely many examples where the ell-adic monodromy groups a
re disconnected over the field of definition of the endomorphism ring. Thi
s is joint work with Victoria Cantoral-Farfan and Davide Lombardo.\n

DESCRIPTION:Title: In
tegral points in families of elliptic curves\nby Stephanie Chan (Unive
rsity of Michigan) as part of Boston University Number Theory Seminar\n\n\
nAbstract\nGiven an elliptic curve over a number field with its Weierstras
s model\, we can study the integral points on the curve. Taking an infinit
e family of elliptic curves and imposing some ordering\, we may ask how of
ten a curve has an integral point and how many integral points there are o
n average. We expect that elliptic curves with any non-trivial integral po
ints are generally very sparse. In certain quadratic and cubic twist famil
ies\, we prove that almost all curves contain no non-trivial integral poin
ts.\n\nSee http://math.bu.edu/research/algebra/seminar.html\n

DESCRIPTION:Title: A
residue map and a Poisson kernel for $GL_3$\nby Peter Gräf (BU) as pa
rt of Boston University Number Theory Seminar\n\n\nAbstract\nIn the classi
cal theory of modular and automorphic forms it has proven to be very usefu
l to realize spaces of such forms in more combinatorial or algebraic ways.
A famous instance of such a realization is the relationship between class
ical modular forms and modular symbols. In this talk\, I will discuss a no
n-archimedean analogue of this construction\, namely the relationship betw
een certain holomorphic discrete series representations on the Drinfeld pe
riod domain and spaces of harmonic cocycles on the Bruhat-Tits building fo
r the group $GL_3$ over a non-archimedean local field of any characteristi
c. The main novelty is that we allow non-trivial coefficients in a situati
on beyond the well-known theory for $GL_2$\, which extends works of Schnei
der and Teitelbaum. I will explain how to construct a residue map and a Po
isson kernel in this situation. Moreover\, I will explain how the existenc
e of the relevant boundary distributions follows from a conjectural non-cr
iticality statement for certain (generalized) automorphic forms.\n
