Maximality of Hamilton action for systems with unilateral links / L. S. Otradnova. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2012. № 4. P. 70-72 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 0].
Hamilton's variational principle for mechanical systems with unilateral constraints is considered. It is shown that the action functional attains its local maximum on the class of variations lying inside the area allowed for the movement. An example is given.
Key words: Hamilton's variational principle, action functional, unilateral constraints.
