Characterization of diffeomorphisms that are symplectomorphisms

Stanisław Janeczko, Zbigniew Jelonek (2009)

Fundamenta Mathematicae

Let $(X, ω_{X})$ and $(Y, ω_{Y})$ be compact symplectic manifolds (resp. symplectic manifolds) of dimension 2n > 2. Fix 0 < s < n (resp. 0 < k ≤ n) and assume that a diffeomorphism Φ : X → Y maps all 2s-dimensional symplectic submanifolds of X to symplectic submanifolds of Y (resp. all isotropic k-dimensional tori of X to isotropic tori of Y). We prove that in both cases Φ is a conformal symplectomorphism, i.e., there is a constant c ≠0 such that $Φ * ω_{Y} = c ω_{X}$ .

Comportement semi-classique du spectre des hamiltoniens quantiques elliptiques

Didier Robert, Bernard Helffer (1981)

Annales de l'institut Fourier

Dans cet article nous généralisons les résultats obtenus par J. Chazarain sur le spectre d’opérateurs de Schrödinger $P (h) = \frac{h^{2}}{2} Δ + V$ lorsque $h \to 0$ . Nous étendons ses résultats aux opérateurs pseudo-différentiels globalement elliptiques d’ordre $m > 0$ .

Convergence results for periodic solutions of nonautonomous Hamiltonian systems

Mario Girardi, Michele Matzeu (1990)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

We prove some stability results for a certain class of periodic solutions of nonautonomous Hamiltonian systems in the case of Hamiltonian functions either with subquadratic growth or homogeneous with superquadratic growth. Thus we extend to the nonautonomous case some results recently established by the Authors for the autonomous case.

Erratum for "Non singular Hamiltonian systems and geodesic flows on surfaces with negative curvature".

Ernesto A. Lacomba, J. Guadalupe Reyes (2000)

Publicacions Matemàtiques

A mistake was found in the reasoning leading to a Lagrangian which we considered as equivalent from the formula for the action S(γ) below the classical mechanical problem (3) on "Non singular Hamiltonian systems and geodesic flows on surfaces with negative curvature", page 271.

Existence of solutions for a nonlinear discrete system involving the $p$ -Laplacian

Xingyong Zhang, Xianhua Tang (2012)

Applications of Mathematics

The existence of solutions for boundary value problems for a nonlinear discrete system involving the $p$ -Laplacian is investigated. The approach is based on critical point theory.
