Title: Asymptotic expansions for linear symmetric hyperbolic systems
       with small parameter

Authors: O. Hawamdeh (Moldova State Univer., Moldova)

Abstract: 
 The boundary layer functions method of Lyusternik-Vishik is used
 to obtain asymptotic expansions of the solutions to the Cauchy problem
 for linear symmetric hyperbolic systems with constant coefficients
 as the small parameter $\varepsilon$ tends to zero.
