Maximum principles around an eigenvalue with constant eigenfunctions
A class of linear operators L+λI between suitable function spaces is considered, when 0 is an eigenvalue of L with constant eigenfunctions. It is proved that L + λI satisfies a strong maximum principle when λ belongs to a suitable pointed left-neighborhood of 0, and satisfies a strong uniform antimaximum principle when λ belongs to a suitable pointed right-neighborhood of 0. Applications are gi...
متن کاملEigenfunctions of linearized integrable equations expanded around an arbitrary solution
Complete eigenfunctions of linearized integrable equations expanded around an arbitrary solution are obtained for the Ablowitz-Kaup-Newell-Segur (AKNS) hierarchy and the Korteweg-de Vries (KdV) hierarchy. It is shown that the linearization operators and the recursion operator which generates the hierarchy are commutable. Consequently, eigenfunctions of the linearization operators are precisely ...
متن کاملMaximum and anti-maximum principles and eigenfunctions estimates via perturbation theory of positive solutions of elliptic equations
In this paper we discuss some new results concerning perturbation theory for second order elliptic partial differential equations related to positivity properties of such equations. We continue the study of some different notions of “small” perturbations and discuss their relations to comparisons of Green’s functions, refined maximum and antimaximum principles, ground state, and the decay of ei...
متن کاملFirst principles semiclassical calculations of vibrational eigenfunctions.
Vibrational eigenfunctions are calculated on-the-fly using semiclassical methods in conjunction with ab initio density functional theory classical trajectories. Various semiclassical approximations based on the time-dependent representation of the eigenfunctions are tested on an analytical potential describing the chemisorption of CO on Cu(100). Then, first principles semiclassical vibrational ...
