DESCRIPTION:Title: Second moment of the central values of Rankin-Selberg $L$
-functions\nby Subhajit Jana (Max Planck Institute for Mathematics\, B
onn) as part of Rényi Institute Automorphic Forms Seminar\n\n\nAbstract\n
Asymptotic evaluation of higher moments of higher degree $L$-values is an
interesting problem and has potential applications towards many questions
in analytic theory of automorphic forms\, e.g. subconvexity of the central
$L$-values. In this talk I will explain a recent result on asymptotic eva
luation of the second moment of $GL(n)\\times GL(n)$ Rankin-Selberg centra
l $L$-values where one of the forms is a fixed cuspidal representation and
the other form is varying in a family containing representations with ana
lytic conductors bounded by $X$ and $X\\to \\infty$. This result has poten
tial to be converted to an asymptotic evaluation of the $2n$'th moment of
the standard $L$-values for $GL(n)$. I will describe the main points of th
e proof which uses spectral decomposition\, integral representation of $L$
-functions\, regularization of Eisenstein series\, and use of analytic new
vectors for $GL_n(\\mathbb{R})$.\n

Abstract\nWe prove a density theorem that bounds the number of automorphic
forms of level $q$ for the group $Sp(4)$ that violates the Ramanujan conj
ecture relative to the amount by which they violate the conjecture\, which
goes beyond Sarnak’s density hypothesis. The proof relies on a relative
trace formula of Kuznetsov type\, and non-trivial bounds for certain $Sp(

ier Lesesvre (Sun Yat-Sen University) as part of Rényi Institute Automorp
hic Forms Seminar\n\n\nAbstract\nThe automorphic representations are one o
f the most important objects in modern number theory\, and a powerful appr
oach is to study them by analytic means\, through their associated $L$-fun
ctions. The values of such $L$-functions are particularly important on the
critical line $\\Re(s) = 1/2$\, and bounding such values is known as the
subconvexity problem.\n\nIn this talk I will present a recent result\, fru
it of a joint work with Mehmet Kiral and Chan Ieong Kuan. We provide a sub
convex bound in the case of $GL(3)$ automorphic forms twisted by a charact
er $\\chi$\, in the hybrid $(t\,\\chi)$ aspect.\n\nOur approach is based o
n Munshi's automorphic circle method\, and this talk will emphasize on the
general strategy as well as the crucial points of the argument.\n

DESCRIPTION:Title: The sup-norm problem in small $p$-adic $K$-types of $GL(
2)$\nby Edgar Assing (University of Bonn) as part of Rényi Institute
Automorphic Forms Seminar\n\n\nAbstract\nThe sup-norm problem asks for goo
d upper bounds on the size of $L^2$-normalised eigenfunctions. In the sett
ing of automorphic forms on ${\\rm GL}_2$ the most studied case are spheri
cal Hecke-Maaß newforms of level $N$. Only very recently an in depth stud
y of non-spherical Hecke-Maaß forms was taken up by Blomer-Harcos-Maga-Mi
lićević. As an $p$-adic analogue of this we replace newforms by forms th
at lie in a small $p$-adic $K$-type. We can prove non-trivial sup-norm bou
nds on average over a basis of this $K$-type when its dimension grows. In
this talk we will make this statement precise and discuss some aspects of
its proof.\n

geodesic. More precisely\, we show how to evaluate the quantum variance of
holomorphic Hecke cusp forms on the vertical geodesic for smooth\, compac
tly supported test functions. The variance is related to an averaged shift
ed-convolution problem that we evaluate asymptotically. We encounter an of
f-diagonal term that matches exactly with a certain diagonal term\, a feat

re the quantum variance computation for the vertical geodesic with the cor
responding computation for the full fundamental domain and we highlight im
