摘要

Let mu be a probability measure on I subset of R with finite moment of all orders and gamma alpha,c(1,2) be a probability measure on C which is expressed by the modified Bessel function. In this paper, we shall first consider operators B-, B+, B degrees and express them in terms of bosonic creation and annihilation operators. Secondly, we shall construct the Hilbert space of analytic L-2 functions with respect to gamma(alpha),c(1,2), HL2(C, gamma alpha, c(1,2)). It will be seen that the SA-transform under certain conditions is a unitary operator from L2 (1, A) onto HL2(C,gamma(alpha),c(12)). Moreover, we shall give explicit examples including Laguerre, Meixner and Meixner-Pollaczek polynomials and explain how the Hilbert space HL2 (C, gamma(alpha), c(1,2)) and B-, B+, B degrees are related from the probabilistic point of view. It will also be given the relationship between the heat kernel on C and gamma(alpha)c(1,2) (subordination property)-
