On unitality conditions for Hom-associative algebras
Yael Fregier, Aron Gohr
In hom-associative structures, the associativity condition is twisted to , with a map in the appropriate category. In the present paper, we c…

Deformation of the Heisenberg Algebra inside
Yael Fregier
We study non-trivial deformations of the natural imbedding of the Lie algebra $\fh_1$ of lower triangular matrices (the Heisenberg Lie algebra) into , where $\mat…

A new cohomology theory associated to deformations of Lie algebra morphisms
Yael Fregier
We introduce a new cohomology theory related to deformations of Lie algebra morphisms. This notion involves simultaneous deformations of two Lie algebras and a homomorphism between…
