Abstract
We use elementary methods to prove an incidence theorem for points and spheres in Fnq. As an application, we show that any point set P⊂F2q with |P|≥5q
determines a positive proportion of all circles. The latter result is
an analogue of Beck’s Theorem for circles which is optimal up to
multiplicative constants.
