Cohomology of $S L_{2}$ and related structures

Klaus Lux, Nham V. Ngo, Yichao Zhang

Let $S L_{2}$ be the rank one simple algebraic group defined over an algebraically closed field $k$ of characteristic $p > 0$ . The paper presents a new method for computing the dimensio…

Eigenform Product Identities For Hilbert Modular Forms

Kirti Joshi, Yichao Zhang

We prove that amongst all real quadratic fields and all spaces of Hilbert modular forms of full level and of weight $2$ or greater, the product of two Hecke eigenforms is not a Hec…

Divisibility properties for weakly holomorphic modular forms with sign vectors

Yichao Zhang

In this paper, we prove some divisibility results for the Fourier coefficients of reduced modular forms of sign vectors. More precisely, we generalize a divisibility result of Sieg…
