RT info:eu-repo/semantics/article T1 CMMSE: Analysis of order reduction when Lawson methods integrate nonlinear initial boundary value problems A1 Cano, Begoña A1 Reguera López, Nuria K1 Exponential methods K1 Lawson methods K1 Nonlinear reaction-diffusion problems K1 Order reduction K1 Matemáticas K1 Mathematics AB In this paper a thorough analysis is carried out of the type of order reductionthat Lawson methods exhibit when used to integrate nonlinear initial boundaryvalue problems. In particular, we focus on nonlinear reaction-diffusion problems, and therefore, this study is important in a large number of practicalapplications modeled by this type of nonlinear equations. A theoretical study ofthe local and global error of the total discretization of the problem is carried out,taking into account both, the error coming from the space discretization andthat due to the integration in time. These results are also corroborated by thenumerical experiments performed in this paper.
