Asymptotics of the number of lattice triangulations of rectangles of width 4 and 5

Stepan Orevkov

Let $f (m, n)$ be the number of primitive lattice triangulations of an $m \times n$ rectangle. We express the limits $lim_{n} f (m, n)^{1/ n}$ for $m = 4$ and $m = 5$ in terms of certain s…

Separating semigroup of genus 4 curves

S. Yu. Orevkov

A rational function on a real algebraic curve $C$ is called separating if it takes real values only at real points. Such a function defines a covering $R C \to RP^{1}$ …
