SUMMARY: (...): Helge PEDERSEN –  Lipschitz normal embeddings in the spac
 e of matrices
DESCRIPTION:: The germ of an algebraic variety is naturally equipped with t
 wo different metrics up to bilipschitz equivalence. The inner metric and t
 he outer metric. One calls a germ of a variety Lipschitz normally embedded
  if the two metrics are bilipschitz equivalent. In this talk we prove Lips
 chitz normal embeddedness of some algebraic subsets of the space of matric
 es. These include the space of matrices\, symmetric matrices and skew-symm
 etric matrices of rank equal to a given number and their closures\, the up
 per triangular matrices with determinant 0 and linear space transverse to 
 the rank stratification away from the origin.\nhttp://www.mathi.uni-heidel
