Abstract:By using the method of recursive sequence and some properties of the solutions to Pell equation,the following conclusions are proved about the system of Diophantine equations x2-22y2=1 and y2-Dz2=1764:if D=2p1…ps, 1≤s≤4 (p1,…,ps are distinct odd primes), then(i)it has only trivial solution = with the exception that D=2×77617;(ii)it has integer solutions =, where D=2×77617; if D=pm(m∈Z+,p is any prime), it has only trivial solution =.
