Super Virasoro algebra

In mathematical physics, a super Virasoro algebra is an extension of the Virasoro algebra (named after Miguel Ángel Virasoro) to a Lie superalgebra. There are two extensions with particular importance in superstring theory: the Ramond algebra (named after Pierre Ramond) and the Neveu–Schwarz algebra (named after André Neveu and John Henry Schwarz). Both algebras have N = 1 supersymmetry and an even part given by the Virasoro algebra. They describe the symmetries of a superstring in two different sectors, called the Ramond sector and the Neveu–Schwarz sector. (Wikipedia).

The magic of matrix multiplication | Linear Algebra MATH1141 | N J Wildberger

We prove the crucial result that matrix multiplication is associative. Along the way we review summation notation and get practice with indices and ranges. ************************ Screenshot PDFs for my videos are available at the website http://wildegg.com. These give you a concise over
