Remarcable Models of Potential Theory

摘要

In the following we present kernels on most countable sets together adjoint kernels associated, determinated by a remarcable measure, the Green function, kernels on ordered sets specially on natural numbers set N~*. Let be X a most countable set. We consider on X σ-algebra Φ(X), hence any map f : X → R_+ is measurable. Obviously any measure μ on X will be determinated by its values on {x}, x∈ X.
