Some existence theorems are obtained by the least action principle for periodic solutions of nonautonomous second-order systems with a potential which is the sum of a subconvex function and a subquadratic function.

Abstract
We prove, by variational arguments, the existence of a solution to the boundary value problem in the half line

where c ≥ 0 and a belongs to a certain class of positive functions. The existence of such a solution in the case c = 0 means that the system (0.1) behaves in significantly different way from its autonomous counterpart. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract In this paper, we develop a direct adaptive control framework for a class of linear discrete‐time uncertain multi‐input–multi‐output (MIMO) systems with exogenous bounded disturbances. The proposed adaptive controller guarantees adaptive stabilization, while the controller does not requ
