Abstract

In this paper we consider the Diophantine equation x2+q2m=2ypx^2+q^{2m}=2y^p where m,p,q,x,ym,p,q,x,y are integer unknowns with m>0,m>0, pp and qq are odd primes and gcd(x,y)=1.\gcd(x,y)=1. We prove that there are only finitely many solutions (m,p,q,x,y)(m,p,q,x,y) for which yy is not a sum of two consecutive squares. We also study the above equation with fixed yy and with fixed q.q.
