Subharmonic Solutions for First-order Hamiltonian Systems
In this article, we study the existence of periodic and subharmonic solutions for a class of non-autonomous first-order Hamiltonian systems such that the nonlinearity has a growth at infinity faster than |x|α, 0 ≤ α < 1. We also study the minimality of periods for such solutions. Our results are illustrated by specific examples. The proofs are based on the least action principle and a generaliz...
متن کاملSubharmonic Solutions of Conservative Systems with Nonconvex Potentials
We consider the system of second order differential equations u" + VG(u) = e(t) = e(t + T), where the potential G: I" -» 1 is not necessarily convex. Using critical point theory, we give conditions under which the system has infinitely many subharmonic solutions. Introduction In this note, we consider the following system of second order differential equations: (1) u" + VG(u) = e(t). Here, G: R...
متن کاملSUBHARMONIC SOLUTIONS FOR NONAUTONOMOUS SUBLINEAR p–HAMILTONIAN SYSTEMS
Some existence theorems are obtained for subharmonic solutions of nonautonomous p -Hamiltonian systems by the minimax methods in critical point theory. Mathematics subject classification (2010): 34C25.
متن کاملBifurcation curves of subharmonic solutions
We revisit a problem considered by Chow and Hale on the existence of subharmonic solutions for perturbed systems. In the analytic setting, under more general (weaker) conditions, we prove their results on the existence of bifurcation curves from the nonexistence to the existence of subharmonic solutions. In particular our results apply also when one has degeneracy to first order — i.e. when the...
متن کاملSingular constrained linear systems
In the linear system Ax = b the points x are sometimes constrained to lie in a given subspace S of column space of A. Drazin inverse for any singular or nonsingular matrix, exist and is unique. In this paper, the singular consistent or inconsistent constrained linear systems are introduced and the effect of Drazin inverse in solving such systems is investigated. Constrained linear system arise ...
