## In this paper, we use the upper and lower solutions method to show that there exists a A\*, such that the nonlinear functional difference equation of the form has at least one positive T-periodic solutions for A E (0, A\*] and does not have any positive T-periodic solutions for A > A\*, where a

In this paper we study differentiability of solutions with respect to parameters in state-dependent delay equations. In particular, we give sufficient conditions for differentiability of solutions in the W 1, p norm (1 p< ). In establishing our main results we make use of a version of the Uniform Co
