On classical doubling method gamma factors for certain depth zero representations

Johannes Girsch, Elad Zelingher · 2026

Piatetski-Shapiro--Rallis discovered an integral representation construction, known as the doubling method, for the tensor product $L$-function of a cuspidal automorphic representation of $G \times \m…

Shapiro's problem on polynomials with large partial sums of coefficients

Marc Technau · 2026

Given a polynomial $\sum_\nu a_\nu X^\nu$ of degree $<d$, bounded by one on the unit disk, how large can $\lvert a_0+a_1+\ldots+a_n \rvert$ ($n<d$) get? This question dates back at least to the 1952 t…
