Abstract:

The stabilizer of N(2,2,0) algebras is studied. By using the stabilizer, congruence decomposition on N(2,2,0) algebras is given. The algebraic structure of the quotient algebra is obtained and also algebraic structure and some properties of a class of converse images under the natural homomorphism are obtained.

Key words: N(2,2,0) algebra; stabilizer; congruence decomposition; natural homomorphism; converse image
