The coset of xx acts as left multiplication by the matrix XX, and the coset of yy acts as left multiplication by the matrix YY. This defines the scalar multiplication for the RR-module structure on Cn\mathbb{C}^n.

Conditions: X,Y∈Mn×n(C)X, Y \in M_{n\times n}(\mathbb{C}) satisfy XY+YX=0XY+YX=0.; R=C⟨x,y⟩/⟨xy+yx⟩R = \mathbb{C}\langle x,y\rangle / \langle xy+yx\rangle.; v∈Cnv \in \mathbb{C}^n.
