摘要：
We construct a representation of solutions for diffusion-wave equations as a sum of two solutions of the first order PDEs. Fractional differentiation is given by the Liouville fractional derivative. The representation is an analogue of the d'Alembert formula known for the wave equation. In the case of an infinite rectangular domain (half-strip), we give relations that connect the traces of the solutions involved in the representation on the boundary of the domain.
