Isometric actions of Heisenberg groups on compact Lorentz manifolds

2015/10/14
We prove results toward classifying compact Lorentz manifolds on
which Heisenberg groups act isometrically. We give a general construction,
leading to a new example, of codimension-one actions—those...
A note on Freiman models in Heisenberg groups
Freiman models Heisenberg groups Number Theory

Green and Ruzsa recently proved that for any $s\ge2$, any small squaring set $A$ in a (multiplicative) abelian group, i.e. $|A\cdot A|s a Freiman $s$-model: it means that there exists a grou...
On critical cases of Sobolev's inequalities for Heisenberg groups

2011/10/17
This paper deal with the problem of Sobolev imbedding in the critical cases. We prove some Trudinger-type inequalities on the whole Heisenberg group, extending to this context the Euclidean results by...
Singular integrals on self-similar sets and removability for Lipschitz harmonic functions in Heisenberg groups

In this paper we study singular integrals on small (that is, measure zero and lower than full dimensional) subsets of metric groups. The main examples of the groups we have in mind are Euclidean space...
Generic Representation Theory of the Additive and Heisenberg Groups

In this paper we give an intimate connection between the characteristic zero representation theories of the Additive and Heisenberg groups, and their characteristic p >0 theories when p is much larger...
