We give estimates of two exponential sums over finite fields for which Weil's estimates fail. Using our estimates and Cohen's sieve method, we prove the conjecture of Hansen and Mullen for the second coefficient in characteristic two when the degree Ն7.
We give an upper bound for some exponential sums over primes, using only sieve methods and Chebyshev's estimate on primes.
A generalization of PLONXA sums is introduced wherein instead of the disjoint union of underlying seta of algebras, the free product of the reducts (of some type) of the algebras is used as underlying set for the new algebra. Preservation of identities is discussed and a number of examples are prese
