The double of representations of Cohomological Hall Algebra for $A_1$-quiver
Published 28 Jul 2014 in math.RT | (1407.7593v2)
Abstract: We compute two representations of COHA for $A_1$-quiver. The two untwisted representations can be combined into a representation of $D_{n+1}$ Lie algebra. The untwisted increasing representation and the twisted decreasing representation can be combined into a representation of a finite Clifford algebra.
