Dense families of modular curves, prime numbers and uniform symmetric tensor rank of multiplication in certain finite fields

Abstract

We obtain new uniform bounds for the symmetric tensor rank of multiplication in finite extensions of any finite field $$\mathbb {F}_p$$ or $$\mathbb {F}_{p^2}$$ where p denotes a prime number $$\ge 5$$ . In this aim, we use the symmetric Chudnovsky-type generalized algorithm applied on sufficiently dense families of modular curves defined over $$\mathbb {F}_{p^2}$$ attaining the Drinfeld–Vladuts bound and on the descent of these families to the definition field $$\mathbb {F}_p$$ . These families are obtained thanks to prime number density theorems of type Hoheisel, in particular a result due to Dudek (Funct Approx Commmentarii Math, 55(2):177–197, 2016).
