摘要：

We deal with the Cauchy and external boundary problems for the nonlinear filtration equation with variable density. For each density we define a class phi of initial functions psi, such that for any psi is-an-element-of phi the problem is uniquely solvable in some set of functions decreasing at infinity with respect to space variables.
