Diophantine quadruples in the ring Z[√2]
Z. Franušić
Sažetak
The set of integers of the quadratic field Q(√d)has the property D(z) if the product of its any two distinct elements increased by z is a perfct square in Q(√d). In case d=2, we prove that there exist infinitely many integer quadruples with the property D(z) if and only if z can be represented as a difference of two squares of integers in Q(√2).
