An action of the affine Yangian $Y_{t_1,t_2}({\widehat{\mathfrak{gl}}}_1)$ on the cohomology of the moduli space of stable sheaves on surfaces

Claudio Pfammatter

We investigate the action of the affine Yangian $Y_{t_1,t_2}({\widehat{\mathfrak{gl}}}_1)$ on the singular cohomology of the moduli space of stable sheaves $\mathcal{M}$ on a smooth…
