Projections of Monogenic AlgebrasLet A and B be associative
algebras treated over a same field F. We say that the
algebras A and B
Isomorphisms of formal matrix incidence rings incidence
algebras of order 4 over a field. We also consider the
isomorphism problem for special classes

On Bol algebras are considered. In the first case, all
algebras with the mentioned conditions are classified up to
isomorphism Structure of associative subalgebras of Jordan operator algebras-subalgebras (Jordan-Banach) of JBW
algebras (dual Jodan-Banach) is implemented naturally by a Jordan
isomorphism Regular solutions of multiplicative-convolution equation in the Vladimirov algebra of the Vladimirov multiplicative
algebra. We also considerthe method of constructing solutions of this equation..
On Inductive Limits for Systems of C*-Algebras that each such an inductive limit is
isomorphic to a reduced semigroup C*-
