Laplacians on Fuzzy Riemann Surfaces
Hiroyuki Adachi, Goro Ishiki, Satoshi Kanno +1
We consider the matrix regularization of scalar fields on a Riemann surface with a general gauge-field background. We propose a construction of the fuzzy version of the Laplacian.

The matrix regularization for Riemann surfaces with magnetic fluxes
Hiroyuki Adachi, Goro Ishiki, Takaki Matsumoto +1
We consider the matrix regularization of fields on a Riemann surface which couple to gauge fields with a nonvanishing magnetic flux. We show that such fields are described as recta…
