Conformal extensions of functions defined on arbitrary subsets of Riemann surfaces
P. M. Gauthier, V. Nestoridis
For a function defined on an arbitrary subset of a Riemann surface, we give conditions which allow the function to be extended conformally. One folkloric consequence is that two co…

Density of polynomials in classes of functions on products of planar domains
P. M. Gauthier, V. Nestoridis
We give sufficient conditions on planar domains for polynomials to be dense in the algebras A and A-infinity of the product of these domains, endowed with their natural topologies.…

On the Instability of the Riemann Hypothesis over Finite Fields
P. M. Gauthier, N. Tarkhanov
We show that it is possible to approximate the zeta-function of a curve over a finite field by meromorphic functions which satisfy the same functional equation and moreover satisfy…
