Universal central extensions of δ-Hom-Jordan Lie superalgebras
The theory of universal central extensions of δ-Hom-Jordan Lie superalgebras is studied.It is shown that the composition of two center extensions of δ-Hom-Jordan Lie superalgebras is not a center extension.Thus,it is necessary to define α-central extensions and universal α-central extensions.And the universal central extension of δ-Hom-Jordan Lie superalgebras is constructed.
