-January 2016

Here we present new results about the asymptotic behavior of average orders of the Fourier coefficients of holomorphic cusp forms by means of meromorphically continuing Dirichlet Series whose coefficients are squares of these partial sums. We do this by decomposing these Dirichlet series into shifted Multiple Dirichlet Series and taking spectral expansions. More recently, we have begun to generalize this construction to non-cusp forms to investigate the generalization of Gauss circle problem to higher dimensions. This is joint work with Chan Ieong Kuan, David Lowry-Duda, and Alexander Walker.

-November 2015

An introduction to primality, Bertrand's postulate, the prime number theorem, and how these all can be extended to arbitrary number fields with the Gaussian integers as a concrete example. A new result, stating a generalization of Bertrand's postulate for number fields, is given. Intended for a mixed audience of undergraduates and faculty. This is joint work with M. Ram Murty.

-October 2015,

Motivated by Gauss's Circle Problem and Dirichlet's Divisor Problem, a talk on the analogous question of finding asymptotics for the partial sums of Fourier coefficients of automorphic forms. More specifically, an introduction to how this problem can be approached via shifted multiple Dirichlet series and our results pursuing this. This is joint work with Chan Ieong Kuan, David Lowry-Duda and Alexander Walker.

I presented the problem of counting indefinite binary quadratic forms with fixed discriminant given certain restrictions on the coefficients, in particular I outlined how to obtain a novel result when the discriminant is a square. I showed that this information could be obtained by investigating the analytic properties of a shifted multiple Dirichlet series comprised of well-understood arithmetic functions and that this analytic information is derived by taking a spectral expansion of a particular truncated Poincaré series inspired by a similar creation due to Jeffrey Hoffstein. This is joint work with E. Mehmet Kıral, Chan Ieong Kuan and Li-Mei Lim.

-June 2014,

In a 2012 paper written with E.M. Kıral, C.I. Kuan and L. Lim, we showed that the square-free coefficients of a half-integral weight cusp form change sign infinitely often, given additional restrictions that this cusp form was a level four Hecke eigenform with real coefficients. More recently, I have been working to loosen those additional restrictions, motivated by a 2013 sign-changing axiomatization theorem due to J. Meher and M. Ram Murty. This updated argument hinges on a better understanding of the Rankin-Selberg L-function of two half-integral weight Hecke eigenforms twisted by an additive character and its functional equation. In this talk I outlined the modified argument and the progress made thus far.

Knowledge about shifted convolution sums can be used to bound different aspects of automorphic L-functions and thus make piecemeal progress toward the General Lindelöf Hypothesis. In joint work with Jeffrey Hoffstein, joint work with E. Mehmet Kıral, Chan Ieong Kuan and Li-Mei Lim, and my own thesis work, we investigated the application of a different sort of truncated Poincaré series, proposed by Hoffstein, in our study of particular shifted sums. These sums have in turn been used to obtain non-trivial asymptotics of triple sums of Fourier coefficients of classical holomorphic cusp forms, a Burgess-type bound for twisted automorphic L-functions, and a smoothed count of square discriminants with bounded coefficients.

-October 2012,

An introduction to shifted convolutions are and how knowledge about them can be used to give subconvexity bounds of automorphic L-functions. I discuss my own work, based off of the work of Jeff Hoffstein, which uses shifted convolutions of holomorphic forms with Maass forms to give a continuation of a triple, shifted Dirichlet series.
