Rings, Polynomials, and Modules

Marco Fontana is professor of algebra at the Università degli Studi "Roma Tre". His research interests lie in the areas of commutative ring theory and related topological aspects, with main focus on multiplicative ideal theory, Prüfer-like conditions and ideal factorizations, and Zariski-Riemann spaces of valuation domains.Sophie Frisch is associate professor of mathematics at Technische Universität Graz, Austria. Her research interests are in commutative algebra and ring theory, including, but not limited to, polynomial mappings and integer-valued polynomials.Sarah Glaz is professor of mathematics at the University of Connecticut. Her research interests lie in the areas of commutative ring theory and homological algebra, with main focus on non-Noetherian properties such as coherence, finite conductor, Gaussian, and Prüfer-like conditions of rings and their modules.Francesca Tartarone is associate professor of algebra atthe Università degli Studi "Roma Tre". Her research interests lie in the area of commutative ring theory with a particular focus on integer valued polynomial rings, star operations on ideals and multiplicative ideal theory properties of Prüfer-like domains. Paolo Zanardo is professor of algebra at the Università di Padova. His research interests lie in the area of commutative rings and their modules, with main focus on modules over valuation domains, ideal class semigroups, algebraic entropies, fully inert Abelian Groups, and factorization of matrices over integral domains.
