Levy processes,ntial equations. The investigation of these processes reduces to the solution of integrodifferential equations of a special form. However, as Kac writes, the solution of the integro-differential equations offers formidable analytic difficulties. Kac was able to overcome these difficulties only for C按时间顺序 发表于 2025-3-27 18:53:08
