Twisted super-Yangians and their representations
Twisted super-Yangians and their representations
Starting with the super-Yangian Y(M|N) based on gl(M|N), we define twisted super-Yangians Y(M|N)±. Only Y+(M|2n) and Y−(2m|N) can be defined, and appear to be isomorphic one with each other. We study their finite-dimensional irreducible highest weight representations.
