The asymptotic profile of $χ_y$-genera of Hilbert schemes of points on K3 surfaces

The Hodge numbers of the Hilbert schemes of points on algebraic surfaces are given by Göttsche's formula, which expresses the generating functions of the Hodge numbers in terms of theta and eta functions. We specialize in this paper to generating functions of the $χ_y(\mathrm{K3}^{[n]})$ genera of Hilbert schemes of $n$ points on K3 surfaces. We determine asymptotic values of the coefficients of the $χ_y$-genus for $n\to \infty$ as well as their asymptotic profile.

Asymptotics of higher order ospt-functions for overpartitions

In this paper we obtain asymptotic formulas for the positive crank and rank moments for overpartitions. Moreover, we show that crank and rank moments are asymptotically equal while the difference is asymptotically positive. This indicates that there exist analogous higher ospt-functions for overpartitions, which we define.

Asymptotics of crank generating functions and Ramanujan congruences

In this paper we obtain asymptotic formulas for the Fourier coefficients of an infinite family of crank generating functions. Moreover we use this result to show that the crank obeys certain inequalities. This implies that the crank can not explain any partition congruences in the usual way beside the three deduced by Ramanujan.
