EXACT SOLUTION OF THE CAUCHY PROBLEM FOR 2-D SCALAR CONSERVATION LAWS WITH CONSTANT COEFFICIENTS IN A CLASS OF DISCONTINUOUS FUNCTIONS
Abstract
In this study a new method for finding exact solution of the Cauchy problem
subject to a discontinuous initial profile for the two dimensional scalar
conservation laws is suggested. For this aim, first, some properties of the
weak solution of the linearized equation are investigated. Taking these
properties into consideration an auxiliary problem having some advantages
over the main problem is introduced. The proposed auxiliary problems also
permit us to develop effective different numerical algorithms for finding the
solutions. Some computer experiments are carried out.
