On a formula for all sets of constant width in 3d

Bernd Kawohl, Guido Sweers

In the recent paper "On a formula for sets of constant width in 2D", Comm. Pure Appl. Anal. 18 (2019), 2117-2131, we gave a constructive formula for all 2d sets of constant width.…

On the uniqueness of eigenfunctions for the vectorial -Laplacian

Ryan Hynd, Bernd Kawohl, Peter Lindqvist

We study a non-linear eigenvalue problem for vector-valued eigenfunctions and give a succinct uniqueness proof for minimizers of the associated Rayleigh quotient.

On the first eigenvalue of the normalized p-Laplacian

Graziano Crasta, Ilaria Fragalà, Bernd Kawohl

We prove that, if is an open bounded domain with smooth and connected boundary, for every the first Dirichlet eigenvalue of the normalized -Laplacian i…

From Symmetry to Monotonicity

Bernd Kawohl, David Krejčiřík

We offer an alternative and shorter proof to a result by Jan J.Ubøe about monotonicity properties of a one-dimensional function that appeared in the Mathematical Intelligencer in 2…

Overdetermined problems for the normalized -Laplacian

Agnid Banerjee, Bernd Kawohl

We extend the symmetry result of Serrin and Weinberger from the Laplacian operator to the highly degenerate game-theoretic -Laplacian operator and show that viscosity solutions…

Generalized elastica problems under area constraint

Vincenzo Ferone, Bernd Kawohl, Carlo Nitsch

It was recently proved that the elastic energy of a closed curve with curvature has a minimizer among all plane, simple, regular and closed…

On the geometry of the -Laplacian operator

Bernd Kawohl, Jiri Horák

The -Laplacian operator is not uniformly elliptic for any and degenerates even more when $p\to \…

The elastica problem under area constraint

Vincenzo Ferone, Bernd Kawohl, Carlo Nitsch

We show that the elastic energy of a closed curve has a minimizer among all plane simple regular closed curves of given enclosed area , and that the minimum is att…

The Neumann eigenvalue problem for the -Laplacian

L. Esposito, B. Kawohl, C. Nitsch +1

The first nontrivial eigenfunction of the Neumann eigenvalue problem for the -Laplacian, suitable normalized, converges as goes to to a viscosity solution of an eig…

The longest shortest fence and sharp Poincaré-Sobolev inequalities

L. Esposito, V. Ferone, B. Kawohl +2

We prove a long standing conjecture concerning the fencing problem in the plane: among planar convex sets of given area, prove that the disc, and only the disc maximizes the length…

Overdetermined boundary value problems for the -Laplacian

G. Buttazzo, B. Kawohl

We consider overdetermined boundary value problems for the -Laplacian in a domain of and discuss what kind of implications on the geometry of the existence o…
