Abstract: In this paper, we extend the method in [TZhu5] to study the energy level $L(\cdot)$ of Perelman's entropy $\lambda(\cdot)$ for K\"ahler-Ricci flow on a Fano manifold. Consequently, we first ...

all ( ,F1,P,X,F) the canonical space for the standard random walk on Z. Thus, denotes the set of paths : N ! Z such that | (n + 1) − (n)| = 1, X = (Xn, n 0) is the canonical coordinate proc...
We show that the law of the overall supremum $\bar{X}_t=\sup_{s\le t}X_s$ of a L\'evy process $X$ before the deterministic time $t$ is equivalent to the average occupation measure $\mu_t(dx)=\int_0^t...

In the paper we study the asymptotic of the tail of
distribution function P(A(X, c) > x) for x + m, where A(X, c) is the
supremum of X(t)-ct over [0, co). In particular, X(t) is the fractional
