Martedì 28 Ottobre 2025, ore 11:00 - Aula 1BC45 - Michele Caselli (SNS)
Abstract
In this talk, we will provide an overview of results on entire saddle-type solutions to phase transition models, as the Allen–Cahn equation in codimension one or the Ginzburg–Landau system in codimension two, highlighting similarities and differences. Then, we will present a new result, obtained in a joint work with Nicola Picenni, regarding the existence of an entire saddle solution of the complex Ginzburg–Landau system in 3D whose zero set is a union of two orthogonal, intersecting lines.
