Asymptotic behavior of solutions of the mixed problem for semilinear hyperbolic equations
The main purpose of this paper is to discuss the optimality of the decay estimate of the mixed problem (MP) for semilinear hyperbolic equations of the type of the Euler-Poisson-Darboux equation and derive the lower bounds of the solutions of MP by making use of the asymptotic property of the solutions BV.
