Homework Help: Find the hamiltonian and lagrangian of a chained system

  1. Dec 7, 2008 #1
    1. The problem statement, all variables and given/known data
    N points at distance a each other -> chain length L=Na. q[tex]_{}n[/tex]
    is the n-point shift.

    2. Relevant equations

    q[tex]\stackrel{}{}..[/tex][tex]_{}n[/tex]=[tex]\Omega[/tex][tex]^{}2[/tex](q[tex]_{}n+1[/tex]+q[tex]_{}n-1[/tex]-2q[tex]_{}n[/tex]

    I must find the hamiltonian and lagrangian of the system.
