On supersingular isogeny graphs of Drinfeld modules

Nikola Veselinov

We study supersingular isogeny graphs of rank-two Drinfeld modules over $A = F_{q} [T]$ . For distinct finite primes $p$ and $q$ of $A$ , we prove that the gr…

Extremal densities for forbidden configurations in $S$ -smooth numbers

Nikola Veselinov

Let $S = {p_{1}, \dots, p_{r}}$ be a finite set of distinct primes, let $Ψ_{S} (X)$ be the number of $S$ -smooth integers not exceeding $X$ , and let $F_{S} (X)$ be the maximum size of a subse…

Solvability of meromorphic equations in elementary functions

Miroslav Marinov, Nikola Veselinov

An equation $f (x) = a$ , where $f$ is a complex meromorphic function and $a \in C$ is a parameter, is solvable in elementary functions if the inverse map $x = f^{- 1} (a)$ can be e…

On the maximal size of $(a, b)$ -town $(mod k)$ families

Nikola Veselinov, Miroslav Marinov

A family $F \subseteq P (n)$ is an $(a, b)$ -town $(mod k)$ if all sets in it have cardinality $a (mod k)$ and all pairwise intersections in it have cardinality $b\pmo…
