We establish a correspondence between a class of Kummer extensions of the rational function "eld and con"gurations of hyperplanes in an a$ne space. Using this correspondence, we obtain explicit curves over "nite "elds with many rational points. Some of our examples almost attain the OesterleH bound.
Let + be an orthogonal measure with compact support of finite length in C n . We prove, under a very weak hypothesis of regularity on the support (Supp +) of +, that this measure is characterized by its boundary values (in the weak sense of currents) of the current [T] 7 ., where T is an analytic su
