Query: Matrix beta-integrals: an overview   First examples of matrix beta-integrals were discovered on 1930-50s by Siegel
and Hua, in 60s Gindikin obtained multi-parametric series of such integrals. We
discuss beta-integrals related to symmetric spaces, their interpolation with
respect to the dimension of a ground field, and adelic analogs; also we discuss
beta-integrals related to flag spaces.
