  • S. V. Pchelintsev

摘要

Each simple right-alternative singular superalgebrais an extended double.The minimal dimension of an extended doublethat is not a linear superalgebra is 10.We consider the 10-dimensional extended doubles of diagonal type and provethat such over an algebraically closed field of characteristic not  $ 2 $ and  $ 3 $ has the structure of a superalgebra depending on two parameters.If the ground field is the field of complexesthen we show that the family of simple superalgebrasfor positive real values of the parameters lacks isomorphic superalgebras.
