Abstract:
In this study, we deal with some Diophantine equations. By using the generalized Fibonacci and Lucas sequences, we obtain all integer solutions of some Diophantine equations such as x(2) - kxy - y(2) = -/+ 1, x(2) - kxy + y(2) = 1, x(2) - kxy - y(2) = -/+(k(2) + 4), x(2) - (k(2) + 4)xy + (k(2) + 4)y(2) = -/+ k(2), x(2) - kxy + y(2) = -(k(2) - 4), and x(2) - (k(2) - 4)xy - (k(2) - 4)y(2) = k(2). Some of the results are known but we think that our proofs are new and different from the others.
