In this volume the author further develops his philosophy of quantum interpolation between the real numbers and the p-adic numbers. The p-adic numbers contain the p-adic integers Zp which are the inverse limit of the finite rings Z/pn. This gives rise to a tree and probability measures w on Zp correspond to Markov chains on this tree. From the tree structure one obtains special basis for the Hilbert space L2(Zp w). The real analogue of the p-adic integers is the interval [-1 1] and a probability measure w on it gives rise to a special basis for L2([-1 1] w) – the orthogonal polynomials and to a Markov chain on finite approximations of [-1 1]. For special (gamma and beta) measures there is a quantum or q-analogue Markov chain and a special basis that within certain limits yield the real and the p-adic theories. This idea can be generalized variously. In representation theory it is the quantum general linear group GLn(q)that interpolates between the p-adic group GLn(Zp) and between its real (and complex) analogue -the orthogonal On (and unitary Un )groups. There is a similar quantum interpolation between the real and p-adic Fourier transform and between the real and p-adic (local unramified part of) Tate thesis and Weil explicit sums.
