On the Springer correspondence for wreath products

You-Hung Hsu, Chun-Ju Lai

We establish a Bruhat decomposition indexed by the wreath product $I^£_{m} ≀ I^£_{d}$ between two symmetric groups -- note that $I^£_{m} ≀ I^£_{d}$ is not a Coxeter group in general. We show…

$0$ -affine quantum groups as K-theoretic Hall algebras

You-Hung Hsu

In this note, we show that the positive part of Arkhipov-Mazin's $0$ -affine quantum group can be realized as the K-theoretic Hall algebra of the type $A$ Dynkin quiver. We then con…
