    Regularized Brownian motion on the Siegel disk of infinite dimension (English)

    The theory of groups of finite dimension and their homogeneous spaces need integration theory fitting the algebraic structure. On the Lie algebra the canonic Hilbertian structure induced by a canonical cocycle exists. This Hilbertian structure defines a formal canonic Laplacian. Then a natural question is to provide an effective construction of the corresponding heat process. This has been done by \textit{P. Malliavin} [C. R. Acad. Sci., Paris, Sér. I, Math. 329, No. 4, 325-329 (1999)] for the diffeomorphism group of the circle. In this paper a process of Brownian motion on the Siegel disk of infinite dimension is constructed.
