These Departmental Seminars are for everyone in Maths. We encourage anyone interested in the subject in general, or in the particular subject of the seminar, to come along. It's a great opportunity to meet people in the Maths Department and join in with our community.

Generalised vectorial infinity-eigenvalue nonlinear problems for L-infinity functionals

In this talk Nikos Katzourakis will discuss the minimisation problem discussed in his recent preprint. This includes the infinity-eigenvalue problem as a special case.

Nikos will describe the existence of a minimiser u-infinity with extra properties, derived as the limit of minimisers of approximating constrained Lp  problems as p to infinity. A central contribution and novelty of this work is that u-infinity is shown to solve a divergence PDE with measure coefficients, whose leading term is a divergence counterpart equation of the non-divergence infinity-Laplacian. The results are new even in the scalar case of the infinity-eigenvalue problem.
