We consider some properties of positive definite binary quadratic forms \(F_{j}\) in the family \(\Omega \). We determine the number of integer solutions of quadratic congruences \(C_{F_{j}}\) and determine the number of rational points on singular curves \(E_{F_{j}}\) related to \(F_{j}\) over finite fields \(\mathbb{F}_{p}\).

On considère quelques propriétés des formes quadratiques binaires définies positives \(F_{j}\) dans la famille \(\Omega \). On détermine le nombre de solutions entières des congruences quadratiques \(C_{F_{j}}\), et le nombre de points rationnels sur des courbes singulières \(E_{F_{j}}\) reliées aux \(F_{j}\) sur des corps finis \(\mathbb{F}_{p}\).
