Abstract.
We prove the existence of hypersurfaces defined over finite fields having a prescribed number of \({\mathbb{F}}_{q}\)-rational points and a prescribed number of non-singular points. Moreover, some results on \({\mathbb{F}}_{q}\)-rational intersections between plane curves, lines and conics, are given.
