Abstract
For a given elliptic curve , let be the number of points on modulo for a prime of good reduction for . Given integer , let be the number of -tuples of primes of good reduction for , for which the equation in the title holds, then on assuming the Generalized Riemann Hypothesis for elliptic curves without CM (and unconditionally if the curves have complex multiplication), I show that for any integer . I conjecture that this result also holds for i.e. this conjecture says that there are arbitrarily long ``elliptic progressions of primes'' i.e. sequences of primes of arbitrary lengths such that .
