Invariant random subgroups of the free group [PDF]
, 2012 Let $G$ be a locally compact group. A random closed subgroup with conjugation-invariant law is called an {\em invariant random subgroup} or IRS for short. We show that each nonabelian free group has a large "zoo" of IRS's.

The automorphism group of the free group of rank two is a CAT(0) group [PDF]
, 2009 We prove that the automorphism group of the braid group on four strands acts faithfully and geometrically on a CAT(0) 2-complex. This implies that the automorphism group of the free group of rank two acts faithfully and geometrically on a CAT(0) 2 ...

Journal of Harbin University of Science and Technology, 2019 In order to solve the problem of whether the matrices generated by two unipotent matrices are unipotency, a new combinatorial property of generators of free groups is obtained by using the matrix logarithmic tool。From the point of the combination of ...

$L^p$ spectral multipliers on the free group $N_{3,2}$ [PDF]
, 2012 Let L be a homogeneous sublaplacian on a stratified Lie group G of homogeneous dimension Q and topological dimension d. By a theorem of Mihlin-Hormander type due to Christ and to Mauceri and Meda, an operator of the form F(L) is of weak type (1,1) and ...

The free splitting complex of a free group I: Hyperbolicity [PDF]
, 2011 We prove that the free splitting complex of a finite rank free group, also known as Hatcher's sphere complex, is hyperbolic.

Random rigidity in the free group [PDF]
, 2011 We prove a rigidity theorem for the geometry of the unit ball in random subspaces of the scl norm in B_1^H of a free group. In a free group F of rank k, a random word w of length n (conditioned to lie in [F,F]) has scl(w)=log(2k-1)n/6log(n) + o(n/log(n))

Systematic Reviews, 2017 Background The use of fat grafting as a reconstructive surgical option is becoming much more common. Adipose-derived stem cells found in fat grafts are believed to facilitate wound healing via differentiation into fibroblasts and keratinocytes and the ...
