On the Behavior of Solutions of the Cauchy Problem for a Hyperbolic Equation with Periodic Coefficients. The Principle of the Limiting Amplitude.

This paper considers the Cauchy problem for a second-order hyperbolic equation with periodic coefficients and zero initial data, and the right-hand side of the equation is the function , . For this problem, the limiting amplitude principle and the asymptotic behavior as are established. [ABSTRACT FROM AUTHOR]
