Abstract

Poisson capacities appeared, first, in the theory of removable boundary singularities for solutions of semilinear elliptic differential equations. It seems that these capacities should play a key role for solving the problem: to describe all positive solutions of the equation $Lu=u^\alpha$ with $\alpha >1$ in a smooth domain. We establish two inequalities for the Poisson capacities which might be useful for this task.
