Аннотация:
В работе построена теория обобщенных решений задачи Коши в целом для уравнений
$$
u_t+\sum_{i=1}^n\frac d{dx_i}\varphi_i(t,x,u)+\psi(t,x,u)=0
$$
в классе ограниченных измеримых функций. Дано определение обобщенного решения
и доказаны теоремы существования, единственности и устойчивости такого решения.
Для доказательства теоремы существования применен “метод исчезающей вязкости”;
в связи с этим предварительно изучается задача Коши для соответствующего параболического уравнения и для решения этой задачи устанавливаются априорные оценки модуля непрерывности в $L_1$, не зависящие от малой вязкости.
