This permits the formulation of an extended twin prime conjecture. Moreover, it is found that the prime numbers subsets contained in Mersenne intervals have cardinalities strongly correlated with the corresponding Mersenne numbers.展开更多

We study Selberg's integral for the automorphic L-function L(s, π△) under GRH. Our results give the information for the number of primes in short intervals attached to Ramanujan automorphic representation.展开更多
