We study infinite intersections of open subschemes and the corresponding infinite intersection of Hilbert schemes. If {U α } is the collection of open subschemes of a variety X containing the fixed point P , then we show that the Hilbert functor of flat and finite families of Spec(O X,P ) = α U α is
Let G be one of the simple groups A or PSL q where q is the power of a n n prime r. Let p be a prime number dividing the order of G. It is proved that if G has a p-Steinberg character, then G is isomorphic to a semi-simple group of Lie type in characteristic p.
## Abstract We investigate the Chow groups of projective determinantal varieties and those of their strata of matrices of fixed rank, using Chern class computations (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
