Title: Oscillation of solutions for forced nonlinear neutral
       hyperbolic equations with functional arguments
       
Author: Yutaka Shoukaku (Kanazawa Univ., Kanazawa Japan)

Abstract:
 This article studies the forced oscillatory behavior of solutions
 to nonlinear hyperbolic equations with functional arguments.
 Our main tools are the integral averaging method and a
 generalized Riccati technique.
