STOCHASTIC CALCULUS FOR MARKOV PROCESSES ASSOCIATED WITH SEMI-DIRICHLET FORMS

抄録

We present a new Fukushima type decomposition in the framework of semi-Dirichlet forms. This generalizes the result of Ma, Sun and Wang [17, Theorem 1.4] by removing the condition (S). We also extend Nakao’s integral to semi-Dirichlet forms and derive Itô’s formula related to it.
