Test for reality of algebraic functions
S. M. Natanzon
In this paper is proved that a complex algebraic function on complexification of a real algebraic curve is equivalent to real algebraic function, if and only if the divisor of prei…

Poincaré's theorem for the modular group of real Riemann surfaces
Antonio F. Costa, Sergey Natanzon
Let be the modular group of surfaces of genus . Each element induces in the integer homology of a surface of genus a symplectic automorphism $H([h…

Higher Arf Functions and Topology of the Moduli Space of Higher Spin Riemann Surfaces
Sergey Natanzon, Anna Pratoussevitch
We prove that any connected component of the space of m-spin structures on compact Riemann surfaces with finite number of punctures and holes is homeomorphic to a quotient of the v…
