Query: A q-Virasoro Algebra at roots of unity, Free Fermions and Temperley Lieb
  Hamiltonians   In this work we introduce a novel q-deformation of the Virasoro algebra
expressed in terms of free fermions, we then realize that this algebra, when
the deformation parameter is a root of unity can be realized exactly on the
lattice. We then study the relations existing between this lattice deformed
Virasoro algebra at roots of unity and the tower of commuting Temperley-Lieb
hamiltonians introduced in a previous work.
