* 세미나 시간: 17:00-18:00 In this talk, we study asymptotic behavior of regular and spectral heat content for various Levy processes. For processes of nite variation, the asymptotic behavior of arbitrary Levy processes in Rd will be investigated. For processes of unbounded variation, we assume some growth condition on the characteristic functions of the processes and we study spectral heat content for arbitrary open sets in a real line. Also stability under integrable perturbation will be discussed. This is a joint work with R. Song and T. Grzywny.
