在对Lévy过程的特征指数或符号的适当条件下,给出了半群的Lp(dx)→Lq(dx)(1 ≤p≤q≤ ∞)模及其梯度的估计.我们的结果有效地适用于Lévy驱动的Ornstein-Uhlenbeck过程类,其中Lévy过程的符号在无穷远附近的渐近行为是已知的。
Under mild conditions on the characteristic exponent or the symbol of Lévy process, we derive explicit estimates forLp(dx) →Lq(dx) (1 ≤p≤q≤ ∞) norms of semigroups and their gradients of the associated Lévy driven Ornstein–Uhlenbeck process. Our result efficiently applies to the class of Lévy driven Ornstein–Uhlenbeck processes, where the asymptotic behaviour near infinity for the symbol of Lévy process is known.
