Reciprocal polynomials and curves with many points over a finite field

Let Fq2 be the finite field with q 2 elements. We provide a simple and effective method, using reciprocal polynomials, for the construction of algebraic curves over Fq2 with many rational points. The…

Parahoric Restriction for GSp(4) and the Inner Cohomology of Siegel Modular Threefolds

For irreducible admissible representations of the group of symplectic similitudes GSp(4,F) of genus two over a p-adic number field F, we obtain the parahoric restriction with respect to an arbitrary…

On the Classification of Low-Degree Ovoids of Q(4,q)

Ovoids of the non-degenerate quadric Q (4 , q ) of PG(4 , q ) have been studied since the end of the ’80s. They are rare objects and, beside the classical example given by an elliptic quadric, only…

Genus bounds for curves with fixed Frobenius eigenvalues

For every finite collection C of abelian varieties over F_q, we produce an explicit upper bound on the genus of curves over F_q whose Jacobians are isogenous to a product of powers of elements of C.
