Periodic solutions of a quasilinear wave equation with variable coefficients
Игорь Алексеевич Рудаков · Sbornik Mathematics · 2007
The existence of time-periodic solutions of the quasilinear equation describing the vibrations of an inhomogeneous string with homogeneous boundary conditions of the 3rd kind is proved. The non-linear term in the equation satisfies the non-resonance condition or has power-like growth. Bibliography: 16 titles.
