Synopsis

This book presents an extension to the theory of discontinuous initial value problems for symmetric hyperbolic linear differential equations, an area previously studied by Courant and Lax. The author generalizes their theory in two respects. First, the author considers more general equations. This generalization is of interest as it allows the inclusion of equations of mathematical physics. Second, the book considers initial boundary value problems rather than pure initial value problems. This has applications to physical problems as it models problems with both time dependence and spatial dependence. The unique existence theorem for weak solutions of such problems is obtained under conditions which allow the coefficient matrices to have multiple eigenvalues. The author provides an analysis of the discontinuities and a reduction to known theorems for problems with smooth initial data. Following on from this, the book presents an asymptotic expansion of solutions of symmetric hyperbolic linear differential equations and proves the asymptotic nature of the formal expansion. Overall, this book advances the theory of discontinuous solutions of hyperbolic partial differential equations, providing a valuable resource for researchers and students in the field.
