%0 Journal Article %T Large deviations for fractional Poisson processes %A Luisa Beghin %A Claudio Macci %J Mathematics %D 2012 %I arXiv %X We prove large deviation principles for two versions of fractional Poisson processes. Firstly we consider the main version which is a renewal process; we also present large deviation estimates for the ruin probabilities of an insurance model with constant premium rate, i.i.d. light tail claim sizes, and a fractional Poisson claim number process. We conclude with the alternative version where all the random variables are weighted Poisson distributed.
