Categorical Equivalences of Finite W-Superalgebras and Clifford Twists

Chih-Whi Chen, Shun-Jen Cheng, Uhi Rinn Suh

Associated with an even nilpotent element $e$ in a basic classical Lie superalgebra $g$ , we study, in full generality, two constructions of finite $W$ -superalgebras, def…

Universal $2$ -parameter $N = 2$ supersymmetric $W_{\infty}$ -algebra

Thomas Creutzig, Volodymyr Kovalchuk, Andrew R. Linshaw +2

The universal $2$ -parameter vertex algebra $W_{\infty}$ of type $W (2, 3, \dots)$ is a classifying object for vertex algebras of type $W (2, 3, \dots, N)$ fo…

Whittaker modules of central extensions of Takiff superalgebras and finite supersymmetric $W$ -algebras

Chih-Whi Chen, Shun-Jen Cheng, Uhi Rinn Suh

For a basic classical Lie superalgebra $s$ , let $g$ be the central extension of the Takiff superalgebra $s \otimes I^ (I^¸)$ , where $I^¸$ is an odd indeter…
