Critical Phenomena on the Bethe Lattice
Rudrajit Banerjee, Nicolas Delporte, Saswato Sen +1
We investigate the critical behavior of a family of -symmetric scalar field theories on the Bethe lattice (the tree limit of regular hyperbolic tessellations) using b…

Analytic semigroups approaching a Schrödinger group on real foliated metric manifolds
Rudrajit Banerjee, Max Niedermaier
On real metric manifolds admitting a co-dimension one foliation, sectorial operators are introduced that interpolate between the generalized Laplacian and the d'Alembertian. This i…

Wick rotation in the lapse, admissible complex metrics, and foliation changing diffeomorphisms
Rudrajit Banerjee, Max Niedermaier
A Wick rotation in the lapse (not in time) is introduced that interpolates between Riemannian and Lorentzian metrics on real manifolds admitting a codimension-one foliation. The de…
