Hopf-Galois module structure of degree p extensions of p-adic fields
Daniel Gil-Muñoz
Let be an odd prime number. For a degree extension of -adic fields , we give a complete characterization of the condition for the ring of integers t…

Hopf-Galois module structure of monogenic orders in cubic number fields
Daniel Gil-Muñoz
For a cubic number field , we consider the -order in of the form , where is a root of a polynomial of the form and $a,b\in\mathbb…

Determining skew left braces of size np
Teresa Crespo, Daniel Gil-Muñoz, Anna Rio +1
We define the twofold semidirect product of two skew left braces, in which both the additive and multiplicative groups are semidirect products of the corresponding groups of the gi…

Additive structure of non-monogenic simplest cubic fields
Daniel Gil-Muñoz, Magdaléna Tinková
We consider Shanks' simplest cubic fields for which the index of a root of the defining parametric polynomial is . For them, we study t…
