Title: One parameter family of elliptic curves and the equation x^4+y^4+kx^2y^2=z^2 Keywords: Elliptic curves, diophantine equations, Mordell-Weil group Abstract: We consider the diophantine equation x^4+y^4+kx^2y^2=z^2, where k∈Z is a parameter. Our aim is to determine for which integers k the equation has a solution in positive integers (x, y, z) and to describe parametrically all nontrivial solutions. References Issue
