On stability, boundedness and square integrability of solutions For fourth-order differential equations of neutral type with variable delay

This paper establishes sufficient conditions to ensure the stability and boundedness of zero solution and square integrability of solutions and their derivatives to neutral-type nonlinear differential equations of fourth order by constructing Lyapunov functionals.
