Mathematisches Kolloquium

We give a survey of various arithmetic properties of Fermat Quotients q_p(a)= (a^{p-1} -1)/p such as p-divisibility, distribution in residue classes modulo p, and properties of the dynamical system x \mapsto q_p(x) \pmod p. These results are related to the classical questions about Wieferich primes, yet their study requires a combination of several modern techniques coming from additive combinatorics, sieve methods the distribution of smooth numbers and bounds of Heilbronn exponential sums.
