Jeśmanowicz’ Conjecture with Congruence Relations. II

Abstract

AbstractLet a, b, and c be primitive Pythagorean numbers such that a2 + b2 = c2 with b even. In this paper, we show that if b0 ≡ ∊(mod a) with ε ∊ {±1} for certain positive divisors b0 of b, then the Diophantine equation ax + by = cz has only the positive solution (x, y, z) = (2, 2, 2).
