Differentiability of Spectral Functions for Relativistic α-Stable Processes with Application to Large Deviations

  • Kaneharu Tsuchida
Article

Abstract

We consider the relativistic α-stable process, a pure jump Markov process generated by \(\mathcal{H}^{\alpha} = (-\Delta + m^{2/\alpha})^{\alpha /2}-m\). Let −C(λ) be the bottom of spectrum of Schrödinger type operator \(\mathcal{H}^{\lambda \mu} = \mathcal{H}^{\alpha} - \lambda \mu\), where μ is a signed Kato measure. We prove the differentiability of C(λ). As an application of it, we establish a large deviation principle for the additive functional \(A_t^{\mu}\) corresponding to the measure μ.
