On sheets of conjugacy classes in good characteristic
Giovanna Carnovale, Francesco Esposito
We show that the sheets for a connected reductive algebraic group G over an algebraically closed field in good characteristic acting on itself by conjugation are in bijection with…
A homological interpretation of the transverse quiver Grassmannians
Giovanni Cerulli Irelli, Gregoire Dupont, Francesco Esposito
In recent articles, the investigation of atomic bases in cluster algebras associated to affine quivers led the second-named author to introduce a variety called transverse quiver G…
Geometry of quiver Grassmannians of Kronecker type and canonical basis of cluster algebras
Giovanni Cerulli Irelli, Francesco Esposito
We study quiver Grassmannians associated with indecomposable representations of the Kronecker quiver. We find a cellular decomposition of them and we compute their Betti numbers. A…
