On the supremum of random cusp forms
Bingrong Huang, Stephen Lester, Igor Wigman +1
A random ensemble of cusp forms for the full modular group is introduced. For a weight- cusp form, restricted to a compact subdomain of the modular surface, the true order of ma…

The hyperbolic circle problem over Heegner points
Dimitrios Chatzakos, Giacomo Cherubini, Stephen Lester +1
For the full modular group, we obtain a logarithmic improvement on Selberg's long-standing bound for the error term of the counting function in the hyperbolic circle problem over H…

Mass equidistribution for Saito-Kurokawa lifts
Jesse Jääsaari, Stephen Lester, Abhishek Saha
Let be a holomorphic cuspidal Hecke eigenform for of weight that is a Saito--Kurokawa lift. Assuming the Generalized Riemann Hypothesis (GRH), w…
