Regularity of Supersolutions
Peter Lindqvist
The regularity for the supersolutions of the Evolutionary p-Laplace Equation is considered. In particular,the equivalence of viscosity supersolutions and p-supercaloric functions (…
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.
The Infinity-Laplacian in Smooth Convex Domains and in a Square
Karl K. Brustad, Erik Lindgren, Peter Lindqvist
We extend some theorems for the Infinity-Ground State and for the Infinity-Potential, known for convex polygons, to other domains in the plane, by applying Alexandroff's method to…
Two formulas for plane paritions
Peter Lindqvist
We give a direct deduction and proof of two identities in the theory of plane partitions. The first one is known to enumerate the traces of plane partitions. The second one comes w…
On -Ground States in the Plane
Erik Lindgren, Peter Lindqvist
We study -Ground states in convex domains in the plane. In a polygon, the points where an -Ground state does not satisfy the -Laplace Equation are character…
The Gradient Flow of Infinity-Harmonic Potentials
Erik Lindgren, Peter Lindqvist
We study the streamlines of -harmonic functions in planar convex rings. We include convex polygons. The points where streamlines can meet are characterized: they lie on cer…
