Analysis Seminar: Variational Problems with Gradient and Pointwise Constraints

Feb 13, 2026, 11:30 AM - 12:30 PM

 

Speaker: Carlos Rautenberg, GMU

Title:  Variational Problems with Gradient and Pointwise Constraints

Abstract:   We consider a class of variational problems involving partial differential operators on non-standard vector-valued measure spaces with divergences (represented by measures or by functions) and with mixed boundary conditions. This class of problems arise from the study of the growth of heterogeneous sandpiles via (Fenchel) duality. The mixed boundary conditions are realized by means of a normal trace characterization of the vectorial measure that extends the notion of the Sobolev trace. We determine existence of solutions, stability, and finalize the talk with numerical tests.
