h-asymptotic stability by fixed point in neutral nonlinear differential equations with delay
We use fixed-point theory to obtain h-asymptotic stability results about the zero solution of nonlinear differential equations with functional delay. Neither boundedness of the deviations nor a fixed sign on the coefficients functions are asked. An explicit estimation of the solutions is obtained and a necessary and sufficient condition is determined. Classical results are improved and generalized.
