Wodzicki residue and minimal operators on a noncommutative 4-dimensional
torus    [PDF]

Andrzej Sitarz

We compute the Wodzicki residue of the inverse of a conformally rescaled Laplace operator over a 4-dimensional noncommutative torus. We show that the straightforward generalization of the Laplace-Beltrami operator to the noncommutative case is not the minimal operator.
