Abstract fractional linear transformations
David Handelman
We begin with (densely-defined) fractional linear transformations (FLT) on (some) Banach algebras and their relatives. This leads to Wedderburn's continued fractions (recursively-d…
Another invariant for AT actions
David Handelman
We construct a collection of numerical invariants for approximately transitive (AT) actions (of ). We use them (sometimes supplemented by other invariants to show that members…
Boundary of the boundary for random walks on groups
David Handelman
We study fine structure related to finitely supported random walks on infinite finitely generated discrete groups, largely motivated by dimension group techniques. The unfaithful e…
A Shapley-Folkman lemma for lattice polytopes
David Handelman
Some occurrences of can be replaced by in a special case of the Shapley-Folkman lemma.
Asymptotic hollowness of lattice simplices
David Handelman
An -tuple consisting of positive integers is said to be asymptotically hollow if there exist infinitely many positive integers such that the…
Random sets and intersections
David Handelman
The following class of problems arose out of vain attempts to show that the Pascal's triangle adic transformation has trivial spectrum. Partition a set of size into sets of siz…
