# On *Q*-Deformations of Postnikov-Shapiro Algebras

**Abstract.**
For any given loopless graph *G*, we introduce *Q*-deformations of
its Postnikov-Shapiro algebras counting spanning trees and forests. We
determine the total dimension of the algebras; our proof also gives a
new proof of the formula for the total dimensions of the usual
Postnikov-Shapiro algebras.
