Teoría de perturbaciones de Brillouin-Wigner: Oscilador armónico perturbado

open access: yesMomento, 1993
An harmonic oscillator is subject to a perturbation [Physical Formula] where [Physical Formula] is an eigenket of the momentum operator. The Brillouin-Wigner perturbation theory is applied to solve the eigenvalue equation of the perturbed Hamiltonian.

Perturbaciones regulares y singulares en problemas de contorno

open access: yes, 2023
La presencia de un pequeño parámetro en un modelo diferencial puede ocasionar pequeñas o grandes perturbaciones en sus soluciones que dificultan los tratamientos computacionales usuales. El objetivo de este trabajo es abordar su influencia a través de diversos ejemplos con perturbaciones regulares y singulares.

Análisis alternativo a la teoría de perturbaciones

open access: yes, 2011
In this thesis work, we construct an alternative approach to perturbation theory of Rayleigh-Schrödinger non-relativistic quantum mechanics by time-dependent Schrödinger equation and matrix algebra. This method has the advantage that provides a compact notation, the correction to the energy and wave function can be calculated in a single operation, and

Análisis de perturbaciones en trayectorias de baja energía

open access: yes, 2020
Este trabajo busca encontrar que rango de perturbaciones pueden hacer que una órbita de baja energía desaparezca entre dos órbitas periódicas Lyapunov, el anterior objetivo es importante para cualquier misión espacial debido a la influencia de las perturbaciones en su trayectoria.
