Continuous Linear Series
Eduardo Esteves, Antonio Nigro, Pedro Rizzo
We parameterize by a fine moduli space all degenerations of linear series to a singular curve which is the union of two smooth components meeting transversally at a single point. F…

Universal deformation rings of a special class of modules over generalized Brauer tree algebras
Jhony F. Caranguay-Mainguez, Pedro Rizzo, José A. Vélez-Marulanda
Let be an algebraically closed field and a generalized Brauer tree algebra over . We compute the universal deformation rings of the periodic string modules over…
