Excision Theory In The Dihedral And Reflexive (Co) Homology Of Algebras
COGENT MATHEMATICS & STATISTICS(2021)
Abstract
In this paper, we study an excision theorem of the dihedral and reflexive (co)homology theory of associative algebras. That is, for such an extension, we obtain a six-term exact sequence in the dihedral cohomology. Also, we present and prove the relation between cyclic and dihedral cohomology of algebras and some examples.
