On the 2-adic valuation of the cardinality of elliptic curves over finite extensions of \(\mathbb {F}_{\varvec{q}} \)
In this paper we study the difference between the 2-adic valuations of the cardinalities \( \# E( \mathbb {F}_{q^k} ) \) ...

Curves of genus two over fields of even characteristic
In this paper we classify curves of genus two over a perfect field k of characteristic two. We find rational models of curves with a given arithmetic structure for the ramification divisor and we give necessary a...
