Iterated extensions and the ramification dichotomy

Mugurel Barcau, Vicenţiu Paşol

Let $K / Q_{p}$ be finite and let $f \in O_{K} [X]$ be monic, of degree at least two, with $f^{'} (X) \in m_{K} O_{K} [X]$ , equivalently $f ˉ \in k [X^{p}]$ . For a co…

Transversal Difference Numbers in Finite Abelian Quotients

Mugurel Barcau, Vicenţiu Paşol, George C. Ţurcaş

Given $H\leq G$ finite abelian groups, a transversal $T\subseteq G$ for $G/H$ has fixed size $|G/H|$, but its ambient difference support $D(T)=T-T$ can vary with the embe…

Logarithmic Density of Rank $\geq 1$ and Rank $\geq 2$ Genus-2 Jacobians and Applications to Hyperelliptic Curve Cryptography

Razvan Barbulescu, Mugurel Barcau, Vicentiu Pasol +1

In this work we study quantitative existence results for genus- $2$ curves over $Q$ whose Jacobians have Mordell--Weil rank at least $1$ or $2$ , ordering the curves by the…

On representations by Egyptian fractions

Florin Ambro, Mugurel Barcau

We give a sharp upper bound for the entries of the representations of a rational number as a sum of Egyptian fractions.
