Almost complex structures, transverse complex structures, and transverse Dolbeault cohomology
Michel Cahen, Jean Gutt, Simone Gutt
We define a transverse Dolbeault cohomology associated to any almost complex structure on a smooth manifold . This we do by extending the notion of transverse complex struct…
Some pseudo-Kähler Einstein -symmetric spaces with a "twin" special almost complex structure
Michel Cahen, Simone Gutt, Manar Hayyani +1
On -symmetric symplectic spaces, invariant almost complex structures -- up to sign -- arise in pairs. We exhibit some -symmetric symplectic spaces, with a pair of "natural" c…
On Twistor Almost Complex Structures
Michel Cahen, Simone Gutt, John Rawnsley
In this paper we look at the question of integrability, or not, of the two natural almost complex structures defined on the twistor space of an even-dimen…
Distributions associated to almost complex structures on symplectic manifolds
Michel Cahen, Maxime Gérard, Simone Gutt +1
We look at methods to select triples consisting of a symplectic manifold endowed with a compatible positive almost complex structure , in terms of the Nijenhui…
Nuclear Group Algebras for Finitely Generated Groups
Michel Cahen, Simone Gutt, Stefan Waldmann
We study completions of the group algebra of a finitely generated group and relate nuclearity of such a completion to growth properties of the group. This extends previous work of…
A possible symplectic framework for Radon-type transforms
Michel Cahen, Thibaut Grouy, Simone Gutt
Our project is to define Radon-type transforms in symplectic geometry. The chosen framework consists of symplectic symmetric spaces whose canonical connection is of Ricci-type. The…
