The Frobenius problem over real number fields

Alex Feiner, Zion Hefty

Given a number field $K$ that is a subfield of the real numbers, we generalize the notion of the classical Frobenius problem to the ring of integers $O_{K}$ of $K$ by desc…

Infinitely wildly ramified arboreal representations for postcritically finite polynomials with potential good reduction

Alex Feiner

Let $K$ be a number field, let $v$ be a finite place of $K$ , let $f \in K [z]$ be a degree $d ⩾ 2$ polynomial with $v ∣ d$ , and let $a \in K$ . We show that if $f$ is postcriticall…
