Goldbach’s problem with primes in arithmetic progressions and in short intervals
Some mean value theorems in the style of Bombieri-Vinogradov’s theorem are discussed. They concern binary and ternary additive problems with primes in arithmetic progressions and short intervals. Nontrivial estimates for some of these mean values are given. As application inter alia, we show that for large odd , Goldbach’s ternary problem is solvable with primes in short intervals with , , and such that has at most prime factors.
