The 2-monoidal structure of symmetric sequences

Patrick Dan, Claudio Pfammatter

We prove a conjecture proposed by Dwyer and Hess (2014), namely that the category of symmetric sequences, when equipped with the composition and matrix monoidal structures, forms a…

An action of the affine Yangian $Y_{t_{1}, t_{2}} (gl_{1})$ on the cohomology of the moduli space of stable sheaves on surfaces

Claudio Pfammatter

We investigate the action of the affine Yangian $Y_{t_{1}, t_{2}} (gl_{1})$ on the singular cohomology of the moduli space of stable sheaves $M$ on a smooth…
