## Potential theory for the $$\alpha$$-stable Schrödinger operator on bounded Lipschitz domains.(English)Zbl 0923.31003

The authors develop the theory of weak Schrödinger operators $$S^\alpha$$ based on the fractional Laplacian $$\Delta^{\alpha/2}$$, which had been introduced in connection with studies of the relativistic stability of matter. The methods used rely mostly on the theory of Markov processes, and the main result of the paper is a conditional gauge theorem.
