Variational principles for nonlinear systems via duality

2026-07-08

Speaker: Amit Acharya (Carnegie Mellon University, USA)

A scheme for generating variational principles for a given system of ODE or PDE with algebraic constraints will be described. It is well known that many physically relevant governing equations, whether time dependent or independent, do not arise from a variational principle. A corresponding...

Quaternionic and almost quaternionic manifolds

2026-07-10

Speaker: Pedro Pessoa (CMUC, UC|UP PhD student)

We will study a characterization of when almost quaternionic manifolds are quaternionic in terms of when a naturally associated differential operator squares to zero....

From phase separation in heterogeneous media to learning training schemes for image denoising

2026-10-29

Speaker: Irene Fonseca (Carnegie Mellon University, USA)

What do these two themes have in common? Both are treated variationally, both deal with energies of different dimensionalities, concepts of geometric measure theory prevail in both, and higher order penalizations are considered. Will learning training schemes for choosing these...
