Chapter 4 Canonical systems in several variables In this chapter we focus on Lie algebras of symmetric type, described in the first section. From these algebras, the quotient representations yield homogeneous spaces, in particular symmetric spaces. The generating functions for the basis of the associated representations are called coherent states. There are connections with the multinomial distribution in probability theory and associated orthogonal polynomials generalizing the Meixner classes to several variables.

There are connections with the multinomial distribution in probability theory and associated orthogonal polynomials generalizing the Meixner classes to several variables. We conclude with a Fourier technique for constructing new classes of orthogonal systems from certain given systems. I. Homogeneous spaces and Cartan decompositions A symmetric Lie algebra has a Cartan decomposition 9 P, JC, C with the following properties: [C, P] c JC, [JC, P] c P, [JC,C] = P EB JC EB C into subalgebras c C That is, C maps Pinto JC by the adjoint map while JC normalizes each of P and C.

Remark. Unless the measures Pt are inlinitely divisible, one will not be able to take t to be a continuous variable. But in any case, we always have Appell systems, analytic in t. What can be guaranteed is that if eH(z) = J e ZX p( dx) then this extends to the discreteparameter process for integer-valued t 2:: O. , positivity may not hold. 3 CANONICAL SYSTEMS The principal feature of (X, D) in the construction of Appell systems is that they are boson variables. 1 Theorem.
