Nilpotent cohomological Hall algebras of surfaces

Duiliu-Emanuel Diaconescu, Mauro Porta, Francesco Sala +2

This paper develops a framework for systematically studying cohomological "Hecke operators" associated with modifications of coherent sheaves on a smooth surface along a fixed…

Topological groupoids with involution and real algebraic stacks

Emiliano Ambrosi, Olivier de Gaay Fortman

To a topological groupoid endowed with an involution, we associate a topological groupoid of fixed points, generalizing the fixed-point subspace of a topological space with involut…

Analytic de Rham stacks of Fargues-Fontaine curves

Johannes Anschütz, Guido Bosco, Arthur-César Le Bras +2

We define and initiate the study of analytic de Rham stacks of relative Fargues-Fontaine curves. To this end, we develop a theory of analytic de Rham stacks with sufficiently stron…
