Walks on generating sets of Abelian groups。
Markov chains on finite sets are used in a great variety of situations
to approximate, understand and sample from their limit distribution. A familiar
example is provided by card shufflin...

We study a Markov chain on generating n-tuples of a ®xed
group which arises in algorithms for manipulating ®nite groups. The
main tools are comparison of two Markov chains on di€erent...

Borel's Conjecture in Topological Groups
Rothberger bounded Borel Conjecture Kurepa Hypothesis Chang’s Conjecture n-huge cardinal
2011/9/21
Abstract: We introduce a natural generalization of Borel's Conjecture. For each infinite cardinal number $\kappa$, let {\sf BC}$_{\kappa}$ denote this generalization. Then ${\sf BC}_{\aleph_0}$ is equ...
A Kronecker-Weyl theorem for subsets of abelian groups

Let N be the set of non-negative integer numbers, T the circle group and c the cardinality
of the continuum. Given an abelian group G of size at most 2c and a countable family E of
infinite subsets ...

Higher index theory certain expanders Gromov monster groups II
2011/2/22
In this paper, the second of a series of two, we continue the study of higher index theory for expanders. We prove that if a sequence of graphs has girth tending to infinity, then the maximal coarse B...

In this paper, the first of a series of two, we continue the study of higher index theory for expanders. We prove that if a sequence of graphs is an expander and the girth of the graphs tends to infin...
On the Relative Weak Asymptotic Homomorphism Property for Pairs of Groups von Neumann Algebras
the Relative Weak Asymptotic Homomorphism Property Pairs Groups von Neumann Algebras
2010/11/9
We provide a direct and elementary proof of the equivalence between the weak asymptotic homomorphism property for the pair of group von Neumann algebras $L(H)\subset L(G)$ and the embedding into $H$ ...
Counting packings of generic subsets in finite groups
Counting generic subsets finite groups
2010/11/9
A packing of subsets $\mathcal S_1,..., \mathcal S_n$ in a group $G$ is a sequence $(g_1,...,g_n)$ such that $g_1\mathcal S_1,...,g_n\mathcal S_n$ are disjoint subsets of $G$. We give a formula for t...

The rainbow connectivity Cayley graphs of Abelian groups
2010/11/9
A path in an edge-colored graph $G$, where adjacent edges may have the same color, is called a rainbow path if no two edges of the path are colored the same. The rainbow connectivity $rc(G)$ of $G$ i...

Constructing free actions p-groups products of spheres
2010/11/11
We prove that, for p an odd prime, every finite p-group of rank 3 acts freely on a finite complex X homotopy equivalent to a product of three spheres
A new subgroup lattice characterization of finite solvable groups

2010/11/18
We show that if G is a finite group then no chain of modular elements in its subgroup lattice L(G) is longer than a chief series. Also, we show that if G is a nonsolvable finite group then every maxi...

In this paper we explore the method of holomorphic induction for unitary representations of Banach--Lie groups. First we show that the classification of complex bundle structures on homogeneous Banac...
