NONLINEAR BOUNDARY-VALUE PROBLEMS FOR THE LYAPUNOV EQUATION IN THE SPACE [L.sub.P]

We study boundary-value problems for a Lyapunov-type equation in the space [L.sub.p](I,[??](H)). Necessary and sufficient conditions for the solvability of the corresponding boundary-value problem are established both in linear and nonlinear cases. The solutions of the linear boundary-value problem...

Zusammenfassung:We study boundary-value problems for a Lyapunov-type equation in the space [L.sub.p](I,[??](H)). Necessary and sufficient conditions for the solvability of the corresponding boundary-value problem are established both in linear and nonlinear cases. The solutions of the linear boundary-value problem are constructed by using the generalized Green operator. It is proposed to find the approximate solutions of the nonlinear equation by using iterative Newton--Kantorovich-type algorithms.
