Formula- first order correction to the n-th wave func

  1. Oct 11, 2015 #1
    Could anybody explain me why indeed we can express the first-order correction to the n-th wave function [tex]\psi_{n}^{1}[/tex] by linear combination [tex]\sum_{m} c_{m}^{(n)}\psi_{m}^{o}[/tex]

    The ##\psi_n## (if defined properly - you didn't specify where they come from) are a base of your vector space of wave functions. You can express every physical wave function with such a linear combination.

    It's Schrodinger equation to first order [tex] \lambda^{1}[/tex] You can see it on page 224 in the Griffiths' Introduction to quantum mechnics

    That page doesn't load.

    In a similar way, but the equations get progressively more messy with each order. I don't have the book here.
