Coalgebraic Approach to the Loday Infinity Category, Stem Differential for $2 n$ -ary Graded and Homotopy Algebras

Mourad Ammar, Norbert Poncin

We define a graded twisted-coassociative coproduct on the tensor algebra $T W$ of any $Z^{n}$ -graded vector space $W$ . If $W$ is the desuspension space $\da V$ of a graded vector spa…

Universal star products

Mourad Ammar, Veronique Chloup, Simone Gutt

One defines the notion of universal deformation quantization: given any manifold $M$ , any Poisson structure $¶$ on $M$ and any torsionfree linear connection $\nabla$ on $M$ , a univ…

Strongly r-matrix induced tensors, Koszul cohomology, and arbitrary-dimensional quadratic Poisson cohomology

Mourad Ammar, Guy Kass, Mohsen Masmoudi +1

We introduce the concept of strongly $r$ -matrix induced ({\small SRMI}) Poisson structure, report on the relation of this property with the stabilizer dimension of the considered q…
