Habibullin, Ismagil T.; Gudkova, Elena V. Classification of integrable discrete Klein-Gordon models. (English) Zbl 1221.81092 Phys. Scr. 83, No. 4, Article ID 045003, 7 p. (2011). Summary: The Lie algebraic integrability test is applied to the problem of classification of integrable Klein-Gordon-type equations on quad graphs. The list of equations passing the test is presented, containing several well-known integrable models. A new integrable example is found; its higher symmetry is presented.
