On the Riemann Problem for a Combustion Model [PDF]

SIAM Journal on Mathematical Analysis, 1993
Summary: This paper studies the Riemann problem for a combustion model and proves that the solution exists globally and the solution converges uniformly, away from the shock, to a travelling wave solution as \(t\to +\infty\). The results are obtained by using the method of characteristics, a maximum principle and that of the equation is a nonlinear ...
