摘要0, V={v|v∈H~1(Ω),v|Γ_1=0}, and V_0={ω|Δω=h in Ω,ω|Γ=0,\forall h∈V}. Let V_0′=the dual space of V_0,a(u,v)=∫_Ω▽u·▽Δvdx, and F(v)=∫_Ω fvdx+∫_(Γ_2)g1Δvds-∫_Γg2\partial v/{\partial \nu}ds, f∈V′_0,g1∈H~(...
In this paper, we give characterizations for Bloch and normal functions. These caracterizations generalize the results of [1].
A REMARK ON PERIODIC SOLUTIONS OF SINGULAR HAMILTONIAN SYSTEMS WITH SUBLINEAR TERMS
Singular Hamiltonian system sublinear pe

In this paper, we prove the existence of multiple periodic solutions for a class of singular Hamiltonian systems with sublinear terms via variational methods.
