Abstract

In this paper, we derive general bounds for the number of rational points on a cubic surface defined over F_q, which constitute an extension of a result due to Weil. Exploiting these bounds, we are able to give a complete characterization of the intersections between the Norm–Trace curve over Fq3 and the curves of the form y= ax³+ bx²+ cx+ d, generalizing a previous result by Bonini and Sala and providing more detailed information about the weight spectrum of one-point AG codes arising from such curve.
