Sov. Math., Dokl. 31, 45-47 (1985); translation from Dokl. Akad. Nauk SSSR 280, 265-268 (1985).
Using the technique of his paper [ibid. 28, 726-729 (1983); translation from Dokl. Akad. Nauk SSSR 273, 1033-1036 (1983; Zbl 0554.34032)] the author studies the asymptotic behavior as \(x\to \infty\) of the decreasing self similar solutions of the generalized sine-Gordon equation \[ \partial^ 2u/\partial z\partial t=\nu \sin u+\mu zt \sin 2u\quad (x=zt). \]
