Schur Eisenstein series and Schur MacMahon series

Henrik Bachmann, Jinbo Yu

We introduce and study two partition-indexed families of quasimodular forms obtained from Schur functions: Schur Eisenstein series and Schur MacMahon series. An explicit transition…

The Young Tableaux Hopf algebra and multiple Schur series

Jinbo Yu

In this paper, we introduce multiple Schur series, which are defined by Schur-type sums over semi-standard Young tableaux and generalize both Schur multiple zeta values and multipl…

Almost-primes in Sun's $x^{2} + n y^{2}$ conjecture

Songlin Han, Jinbo Yu

In 2015 Zhi-Wei Sun proposed the conjecture that any integer $n > 1$ admits a partition $n = x + y$ with integers $x, y > 0$ such that $x + n y$ and $x^{2} + n y^{2}$ are simultaneously p…
