Mean time until break of a chain with N = 2, 3, 4 oscillators / S. A. Muzychka. //Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2013. ? 4. P. 46-51 [Moscow Univ. Math. Bulletin. Vol. 68, N 4, 2013.].

An asymptotic formula is obtained for an average time of rupture for a chain of harmonic oscillators consisted of N = 2, 3, 4 particles with nearest-neighbor interaction and random external force.

Key words: system of harmonic oscillators, large deviations, Markov process, mean exit time.
