β¦ Synopsis
Let M~ be the supremum of a random walk drifting to -oo which is generated by the partial sums of a sequence of independent identically distributed random variables with a common distribution F. We prove that the moment generating function Eexp(sM~) is a rational function if and only if the function f~'~ exp(sx)F(dx) is rational.

Suppose that the random vector (X 1 , ..., X q ) follows a Dirichlet distribution on R q + with parameter ( p 1 , ..., p q ) # R q + . For f 1 , ..., f q >0, it is well-known that . In this paper, we generalize this expectation formula to the singular and non-singular multivariate Dirichlet distrib
