Diagonal actions and Borel equivalence relations
We investigate diagonal actions of Polish groups and the related intersection operator on closed subgroups of the acting group. The Borelness of the diagonal orbit equivalence relation is characterized and is shown to be connected with the Borelness of the intersection operator. We also consider relatively tame Polish groups and give a characterization of them in the class of countable products...
متن کاملDiagonal Similarity and Equivalence for Matrices
the cyclic products of matrices and diagonal similarity. In this paper we consider diagonal similarity for matrices, which may be infinite, and whose elements lie in a (possible non-commutative) group G with O. Let H be a subgroup of a group G and let A be an irreducible square matrix with entries in GO. In Theorem 3.4, we give necessary and sufficient conditions for the existence of a matrix B...
متن کاملDiagonal Actions in Positive Characteristic
We prove positive characteristic analogues of certain measure rigidity theorems in characteristic zero. More specifically we give a classification result for positive entropy measures on quotients of SLd and a classification of joinings for higher rank actions on simply connected absolutely almost simple groups.
متن کاملOne-sided simultaneous inequalities and sandwich theorems for diagonal similarity and diagonal equivalence of nonnegative matrices
Results on the simultaneous scaling of nonnegative matrices involving one sided inequalities are presented. These are applied to scalings involving two sided inequalities. The proofs are graph theoretic. The setting is generalized to matrices with elements in lattice ordered Abelian groups with 0.
متن کاملApplications of Measure Rigidity of Diagonal Actions
Furstenberg and Margulis conjectured classifications of invariant measures for higher rank actions on homogeneous spaces. We survey the applications of the partial measure classifications result by Einsiedler, Katok, and Lindenstrauss to number theoretic problems. Mathematics Subject Classification (2010).
