Abstract: We show that the trace decategorification, or zeroth Hochschild homology, of the twisted Heisenberg category defined by Cautis and Sussan is isomorphic to a quotient of $${W^-}$$W-, a subalgebra of $${W_{1+\infty}}$$W1+∞ defined by Kac, Wang,… read more here.

Abstract: Abstract In this article, we investigate Lie bialgebra structures on the deformed twisted Heisenberg–Virasoro Lie algebra. Sufficient and necessary conditions for this type Lie bialgebra structures to be triangular coboundary are given. Communicated by K.… read more here.
