Abstract

For t[0,1] t \in [0,1] let H2nt=(mi+j)i,j=0nt\underline{H}_{2\lfloor nt \rfloor} = ( m_{i+j})_{i,j=0}^{\lfloor nt \rfloor} denote the Hankel matrix of order 2nt2\lfloor nt \rfloor of a random vector (m1,,m2n)(m_1,\ldots ,m_{2n}) on the moment space M2n(I)\mathcal{M}_{2n}(I) of all moments (up to the order 2n2n) of probability measures on the interval IRI \subset \mathbb{R} . In this paper we study the asymptotic properties of the stochastic process {logdetH2nt}t[0,1]\{ \log \det \underline{H}_{2\lfloor nt \rfloor} \}_{t\in [0,1]} as nn \to \infty. In particular weak convergence and corresponding large deviation principles are derived after appropriate standardization.
