On the Number of Solutions of an Equation Over a Finite Field
James W. P. Hirschfeld, Gábor Korchmáros · Bulletin of the London Mathematical Society · 2001
The Stöhr–Voloch approach is used to obtain a new bound for the number of solutions in (Fq)2 of an equation f(X, Y) = 0, where f(X, Y) is an absolutely irreducible polynomial with coefficients in a finite field Fq.
