On the Diophantine equation X2+pm=p1n1p2n2
Abstract
We consider the Diophantine equation X2+pm=p1n1p2n2, where p,p1,p2 are distinct odd primes. Using factorizations in quadratic fields, sharp bounds for linear forms in two p-adic logarithms, elementary methods, and known results on exponential Diophantine equations, we obtain explicit bounds for m,n1,n2, and consequently the finiteness of the number of solutions for fixed p,p1,p2.
