In this paper, we use probabilistic methods of excursion theory for Lévy processes in order to value some exotic options in general exponential Lévy models. AMS 2000 Subject Classification : Primary: 60G51, 91B28, 91B70. JEL Classification: C13.

An SDDS-2000 server currently manages only buckets in its RAM storage [C01]. Several buckets can coexist. When many files are created however, RAM storage space may not be sufficient for all the buckets simultaneously. When an application requests a bucket, but there is not enough room in RAM for it, one can evict some buckets to the disk. We define a number of promising eviction strategies. Ou...

In repeated games with di®erential information on one side, the labelling \general case" refers to games in which the action of the informed player is not known to the uninformed, who can only observe a signal which is the random outcome of his and his opponent's action. Here we consider the problem of minimizing regret (in the sense ̄rst formulated by Hannan [8]) when the information available...

We show that any connected regular graph with d + 1 distinct eigenvalues and odd-girth 2d + 1 is distance-regular, and in particular that it is a generalized odd graph. 2010 Mathematics Subject Classification: 05E30, 05C50; JEL Classification System: C0
