Summary: We give two examples of nonuniqueness of generalized solutions of pressureless gas dynamics systems. In both of these examples, the presence of the Dirac delta-function leads to nonuniqueness.
Classification : 35L65, 35L67
Keywords: zero-pressure gas dynamics system, vacuum state, delta-shock solution
