Dynkin's formula `between' stopping times?
Hi, I was wondering about a simple generalisation of the well-known Dynkin's formula for Markov processes. I'm interested in a discrete-state continuous-time Markov process (not sure the discrete-state bit matters though), say X(t). Denote the state-space by X and the infinitesimal generator (matrix) by A. Let... 3 Jun 2010 14:32

a question on differentiability
suppose f:A->B ; g:A->C and h:C->B be such that f = hog by composite function theorem if h and g are differentiable then so is f but does differentiability of f and g imply differentiability of h ? or does differentiability of f and h imply differentiability of g ? please reply. ... 1 Jun 2010 10:52

Pasting Lemma
Does the following form of the pasting lemma hold for all spaces? If D is dense, K closed, U open, X = K \/ U, f:X -> Y and f is continuous over U and over K \/ D, then f is continuous. It is a result of the following which is known to hold for metric spaces. If D is dense, U open and dense, A = bd U \/ U/\D... 7 Jun 2010 14:19
