Título:Teoremas de semiespacio para superficies con curvatura media predeterminadaImpartida por: Antonio Bueno
Abstract:
Motivados por el teorema de semiespacio clásico de Hoffman y Meeks para superficies mínimas en \(\mathbb{R}^3\), el objetivo de esta charla es obtener resultados de tipo semiespacio para superficies inmersas en el espacio Euclideo \(\mathbb{R}^3\) cuya curvatura media viene dada por una función predeterminada dependiendo de su aplicación de Gauss.

Title: Hydrodynamic limit of an active-passive lattice gas.
Abstract:
In this talk, the speaker discusses a model mixture of active (self-propelled) and passive (diffusive) particles with non-reciprocal effective interactions (i.e., forces that violate Newton's third law). The speaker derives the hydrodynamic PDE limit for the particle densities, which is not a Wasserstein gradient flow of any free energy, consistent with the microscopic model exhibiting non-equilibrium steady states. The talk explores the emergence of collective behaviour, including phase separation and dynamical (travelling) steady states.
