Perturbation theory for nonlinear Dirichlet problems.
Perturbations and nonlinear harmonic spaces. (Perturbations et espaces harmoniques non linéares.)
Polar sets for supersolutions of degenerate elliptic equations.
Potential spaces on fractals
We introduce potential spaces on fractal metric spaces, investigate their embedding theorems, and derive various Besov spaces. Our starting point is that there exists a local, stochastically complete heat kernel satisfying a two-sided estimate on the fractal considered.
Potential theory and Lefschetz theorems for arithmetic surfaces
Potential theory of quasiminimizers.
Properties of the mappings that are close to the harmonic mappings. II.
