We present an algebraic approach to string theory, using a Hamiltonian reduction of N = 2 WZW models. An embedding of sl(1|2) in a Lie superalgebra determines a niltopent subalgebra. Chirally gauging this subalgebra in the corresponding WZW action leads to an extension of the N = 2 superconformal algebra. We classify all the embeddings of sl(1|2) into Lie superalgebras: this provides an exhaust...

The conditions of β−algebra is enforced into the structure cubic intuitionistic fuzzy settings. Furthermore, concept β− subalgebra expressed and its pertinent properties were explored. Also, discussed about level set β−subalgebras furnished some fascinating results on cartesian product β−subalgebra. Moreover, notion -normed have been introduced relevant are studied.
