Spectral Asymptotics on Compact Manifolds and Related Problems in Analytic Number Theory
Abstract: We review and discuss the remainder term of Weyl's Law for the spectral
counting function on closed compact Riemannian manifolds. Since the celebrated
theorem of Hormander (1968) there has been much effort towards improving the
estimate of the remainder term in Weyl's law for specific classes of manifolds.
Interestingly, in some cases these problems and the methods used to attack them
are related to classic lattice counting problems and open conjectures in analytic
number theory including the Gauss Circle Problem, the Dirichlet Divisor Problem,
and the calculation of the meansquare average of the Riemann zeta function on the
critical line. I will discuss my own results for Weyl's law on Heisenberg Manifolds
(the first, natural, noncommutative generalization of tori) and new results I have
obtained in the Dirichlet Divisor Problem.
The speaker is a UFA candidate in the Department of Mathematics and will also give
the DGMPPDE Seminar, Tuesday, October 2nd at 2:00 p.m. in WMAX 110 (PIMS Facility).
Refreshments will be served at 3:45 p.m. (Math Lounge, MATX 1115).
