On solvability of a periodic problem for a nonlinear telegraph equation
Sergei Sergeevich Kharibegashvili, Отар Михайлович Джохадзе · Siberian Mathematical Journal · 2016
The time-periodic problem is studied for a nonlinear telegraph equation with the Dirichlet–Poincaré boundary conditions. The questions are considered of existence and smoothness of solutions to this problem.
