Khovanov-Rozansky homologies, Bott-Samelson spaces and twisted cohomology

Autor: Mejia-Gomez, Tomas

By means of Rasmussen's formulation of Khovanov-Rozansky homology originally given over $\mathbb{Q}$ in arXiv:math/0607544, we compare different flavors of $\mathfrak{sl}(n)$ link homology with the link invariants obtained by Kitchloo in arXiv:1910.0

Torelli theorem for the moduli stack of vector bundles with fixed determinant

Autor: Alfaya, David, Biswas, Indranil, Gómez, Tomás L., Mukhopadhyay, Swarnava

Given any irreducible smooth complex projective curve X, of genus at least two, consider the moduli stack of vector bundles on X of fixed rank and determinant. It is proved that the isomorphism class of the stack uniquely determines the isomorphism c

A guide to moduli theory beyond GIT

Autor: Gómez, Tomás L., Herrero, Andres Fernández, Zamora, Alfonso

In this survey we provide an overview of some recent developments in the construction of moduli spaces using stack-theoretic techniques. We will also explain the analogue of Harder-Narasimhan stratifications for general stacks, known as $\Theta$-stra
