Timetable + Abstracts






  • This workshop is dedicated to the memory of our dear friend Piet Hemker who passed away in May 2019

    Piet worked at CWI (the Centre for Mathematics & Computer Science) in Amsterdam from 1970 until his retirement in 2006 and was a CWI Fellow since 2001. From 1989 until his retirement, he was also an endowed professor at the University of Amsterdam. Piet contributed with important innovative scientific research to many areas of numerical mathematics, including, inter alia, multigrid methods, defect correction, numerical methods for compressible flows, and manifold mapping. Of particular relevance to this workshop, he published more than 20 papers with G.I. Shishkin on singular perturbation problems and proposed the famous Hemker test problem in J. Comput. Appl. Math. in 1996. In 2006 Piet became a Knight in the Order of the Netherlands Lion (Ridder in de Orde van de Nederlandse Leeuw).

A two day workshop is being organised by the Department of Mathematics and Statistics at the University of Limerick, Limerick, Ireland, in cooperation with the MACSI (Mathematics Applications Consortium for Science and Industry).

The aim of the workshop is to bring together people, in the mathematics and general scientific community, who have particular interests in the development and applications of numerical methods for problems that exhibit layer phenomena, such as boundary/interior layers in fluid flow and other applications.

The previous meeting in this series was 16th Workshop on Numerical Methods for Problems with Layer Phenomena, University of Seville, Spain, February 2019.
