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

2. Relevant equations

q$$\stackrel{}{}..$$$$_{}n$$=$$\Omega$$$$^{}2$$(q$$_{}n+1$$+q$$_{}n-1$$-2q$$_{}n$$

I must find the hamiltonian and lagrangian of the system.
