Temporal periodic solutions to nonhomogeneous quasilinear hyperbolic equations driven by time-periodic boundary conditions

Abstract: We consider the temporal periodic solutions to general nonhomogeneous quasilinear hyperbolic equations with a kind of weak diagonal dominant structure. Under the temporal periodic boundary conditions, the existence, stability and uniqueness of the time-periodic classical solutions are obtained.Moreover, the W2, regularity and stability around the time-periodic solutions are discussed. Our results reveal that the feedback boundary control with dissipative structure can stabilize the K-weakly diagonally dominant nonhomogeneous quasilinear hyperbolic system around the temporal periodic solution.
