Abstract

In this paper, we establish hybrid results on Diophantine approximation with primes from short intervals. In particular, we prove the following result in a slightly modified form: If α\alpha is an irrational number having a continued fraction expansion with bounded terms (in particular, if α\alpha is a quadratic irrational), then the number of primes pp in the interval (XY,X](X-Y,X] satisfying pα<δ||p\alpha||<\delta is asymptotically equal to 2δY/logX2\delta Y/\log X, provided that X10X\ge 10, X2/3+εYX/2X^{2/3+\varepsilon}\le Y\le X/2 and Xεmax{X1/4Y1/2,X2/3Y1}δ1/2X^{\varepsilon}\max\left\{X^{1/4}Y^{-1/2},X^{2/3}Y^{-1}\right\}\le \delta\le 1/2.
