Minimal degree of an isogeny between a supersingular elliptic curve and its conjugate

Yves Aubry, Roger Oyono, Christelle Vincent

The paper establishes a bound on the minimal degree of an isogeny between a supersingular elliptic curve over the algebraic closure of a finite field and its Frobenius conjugate, s…

Maximal curves with respect to quadratic extensions over finite fields

Yves Aubry, Fabien Herbaut, Julien Monaldi

We propose a detailed study of a canonical bound which relates the numbers of rational points of a curve over a finite field with that over its quadratic extension. Alternative pro…

Rational points on smooth surfaces in over finite fields

Yves Aubry, José Felipe Voloch

We improve a bound due to the second author on number of rational points on smooth surfaces in over finite fields and look at families of surfaces that achieve or ne…

Trinomials with high differential uniformity

Yves Aubry, Fabien Herbaut, Ali Issa

Comparisons of arithmetic and geometric monodromy groups coupled with the Chebotarev density theorem enable to obtain families of trinomials defined over finite fields of even char…

Inseparable endomorphisms and rank-2 sublattices of the Gross lattice

Yves Aubry, Christelle Vincent

We answer a question posed by Love asking about a correspondence between isogenies from a supersingular elliptic curve to its Frobenius base-change and rank-2 sublattices of its Gr…

Maximum number of rational points on hypersurfaces in weighted projective spaces over finite fields

Yves Aubry, Marc Perret

An upper bound for the maximum number of rational points on an hypersurface in a projective space over a finite field has been conjectured by Tsfasman and proved by Serre in 1989.…
