How to avoid order reduction when Lawson methods integrate nonlinear initial boundary value problems Cano, Begoña Reguera López, Nuria Order reduction Lawson methods Reaction-diffusion Initial boundary value problems It is well known that Lawson methods suffer from a severe order reduction when integrating initial boundary value problems where the solutions are not periodic in space or do not satisfy enough conditions of annihilation on the boundary. However, in a previous paper, a modification of Lawson quadrature rules has been suggested so that no order reduction turns up when integrating linear problems subject to time-dependent boundary conditions. In this paper, we describe and thoroughly analyse a technique to avoid also order reduction when integrating nonlinear problems. This is very useful because, given any Runge–Kutta method of any classical order, a Lawson method can be constructed associated to it for which the order is conserved. 2023-11-21T10:47:38Z 2023-11-21T10:47:38Z 2023-11-21T10:47:38Z 2021-06 info:eu-repo/semantics/article 0006-3835 http://hdl.handle.net/10259/8073 10.1007/s10543-021-00879-8 1572-9125 eng BIT Numerical Mathematics. 2022, V. 62, n. 2, p. 431-463 https://doi.org/10.1007/s10543-021-00879-8 info:eu-repo/grantAgreement/AEI/Plan Estatal de Investigación Científica y Técnica y de Innovación 2017-2020/PGC2018-101443-B-I00/ES/RESOLUCION NUMERICA PRECISA EN TIEMPO DE ECUACIONES EN DERIVADAS PARCIALES/ info:eu-repo/grantAgreement/Junta de Castilla y León//VA169P20//Inversión en tecnologías limpias y políticas medioambientales: Modelización matemática y análisis mediante juegos dinámicos/ info:eu-repo/semantics/openAccess Springer
