Summary: We consider the question of determining the maximum number of $$\mathbb{F}_{q}$$-rational points that can lie on a hypersurface of a given degree in a weighted projective space over the finite field $$\mathbb{F}_{q}$$, or in other words, the maximum number of zeros that a weighted homogeneous polynomial of a given degree can have in the corresponding weighted projective space over $$\mathbb{F}_{q}$$. In the case of classical projective spaces, this question has been answered by J.-P. Serre. In the case of weighted projective spaces, we give some conjectures and partial results. Applications to coding theory are included and an appendix providing a brief compendium of results about weighted projective spaces is also included.
