Wave equations and symmetric first-order systems in case of low regularity
Clemens Hanel, Günther Hörmann, Christian Spreitzer +1
We analyse an algorithm of transition between Cauchy problems for second-order wave equations and first-order symmetric hyperbolic systems in case the coefficients as well as the d…

Symmetric hyperbolic systems in algebras of generalized functions and distributional limits
Guenther Hoermann, Christian Spreitzer
We study existence, uniqueness, and distributional aspects of generalized solutions to the Cauchy problem for first-order symmetric (or Hermitian) hyperbolic systems of partial dif…
