The geometry of planar -harmonic mappings: convexity, level curves and the isoperimetric inequality
Tomasz Adamowicz
We discuss various representations of planar -harmonic systems of equations and their solutions. For coordinate functions of -harmonic maps we analyze signs of their Hessians…

Regularity of -superharmonic functions, the Kellogg property and semiregular boundary points
Tomasz Adamowicz, Anders Björn, Jana Björn
We study various boundary and inner regularity questions for -(super)harmonic functions in Euclidean domains. In particular, we prove the Kellogg property and introduce a…
