Lei, Yuanning Delta waves for elastic dynamic system. (Chinese. English summary) Zbl 0920.35091 Acta Math. Sci. (Chin. Ed.) 18, No. 4, 361-370 (1998). Summary: We discuss the propagation of delta waves for the semilinear elastodynamic system. Under the conditions of which the nonlinear items are globally bounded and Lipschitz continuous, we proved the existence of delta waves for the semilinear elastodynamic systems.
