Superalgebras and Algebras with Involution: Classifying Cubic Codimension Sequences

Yan-Hong Bao, Jiang-Nan Xu, Yuan-Feng Zhang

A $φ$ -algebra is either a superalgebra or an algebra with involution. In this paper, we study $T^{φ}$ -ideals associated with unital $φ$ -algebras whose $φ$ -codimension…

Operad and cohomology of associative algebras with generalized derivations

Jiang-Nan Xu, Yan-Hong Bao

An associative algebra with a generalized derivation is called an AsGDer triple. We introduce the operad that encodes AsGDer triples, and prove it is a Koszul operad. Using its Kos…
