The damped Fermi-Pasta-Ulam oscillator
The system q¨k + γq˙k = V 0 (qk+1 − qk ) − V 0 (qk − qk−1 ) (k = 1, . . . , N − 2) is considered, where 0 < γ = const., 2 < N ∈ N, V : (A, B) → R (−∞ ≤ A < B ≤ ∞) is a strictly convex, two times continuously differentiable function. We connect to the system three kinds of boundary condition...
