Asymptotics of generalized Bessel functions and weight multiplicities via large deviations of radial Dunkl processes

J Huang, C McSwiggen - Probability Theory and Related Fields, 2024 - Springer
This paper studies the asymptotic behavior of several central objects in Dunkl theory as the
dimension of the underlying space grows large. Our starting point is the observation that a …
