Abstract

Let \(\{X_t\}_{t \ge 0}\) be the symmetric \(\alpha \)-stable process with generator \(H = (-\Delta )^{\alpha /2}\) for \(0 < \alpha \le 2\). For a positive Radon measure \(\mu \), we define the Schrödinger operator \(H^\mu = H - \mu \) and consider the fundamental solution of the equation \(\partial u/\partial t = - H^{\mu } u\). If \(\mu \) is critical, the behavior of the fundamental solution is different from that of the transition density function of \(\{X_t\}_{t \ge 0}\). In this paper, we give a certain ergodic-type limit theorem for fundamental solutions of critical Schrödinger operators.
