The Hölder Exponent for Radially Symmetric Solutions of Porous Medium Type Equations
Published online by Cambridge University Press: 20 November 2018
Extract
The density u(x, t) of an ideal gas flowing through a homogeneous porous media satisfies the equation Here m > 1 is a physical constant and u also satisfies the initial condition If the initial data is not strictly positive it is necessary to work with generalized solutions of the Cauchy problem (1), (2) (see [1]). By a weak solution we shall mean a function u(x, t) such that for (in the sense of distributions) and
