Heat kernel for flat generalized Laplacians with anisotropic scaling

Understand

We calculate the closed analytic form of the solution of heat kernel equation for the anisotropic generalizations of flat Laplacian.

• We consider a UV as well as UV/IR interpolating generalizations.
• In all cases, the result can be expressed in terms of Fox-Wright psi-functions.
• We perform different consistency checks, analytically reproducing some of the previous numerical or qualitative results, such as spectral dimension flow.
