Klimek S., Lesniewski A. Quantum Riemann Surfaces for Arbitrary Planck's Constant (26K, plain TeX) ABSTRACT. We continue our study of quantum Riemann surfaces initiated in [1, 2, 3]. We construct a one parameter family of deformations of compact Riemann surfaces of genus $g\geq 2$. Our construction does not require any discretness condition on the value of Planck's constant. It coincides with the construction of [2] in the case when Planck's constant assumes the discrete set of values dictated by geometric quantization.
