Continuity of multivariate rational functions
Ali Sinan Sertoz
If the denominator of a rational function of several variables is sum of even powers and the numerator is a monomial, then we give a numerical criterion, using the exponents involv…
A Scientific Biography of Cahit Arf (1910-1997)
Ali Sinan Sertoz
In this paper we analyze both the scientific activities of Cahit Arf, a Turkish mathematician, and the social context in which he worked. We also discuss his work and social enviro…
Irreducible Heegner Divisors in the Period Space of Enriques Surfaces
Caner Koca, Ali Sinan Sertoz
Reflection walls of certain primitive vectors in the anti-invariant sublattice of the K3 lattice define Heegner divisors in the period space of Enriques surfaces. We show that depe…
Which Singular K3 Surfaces Cover an Enriques Surface
Ali Sinan Sertoz
We determine the necessary and sufficient conditions on the entries of the intersection matrix of the transcendental lattice of a K3 surface for the K3 surface to doubly cover an E…
