There will be a FNRS Contact Group in Numerical Analysis on Friday 5 December 1997, in Faculte Polytechnique de Mons, Salle Academique, boulevard Dolez 31, B-7000 Mons. The theme is: 'Numerical methods in ordinary and partial differential equations'. The two main invited speakers are: W. Schiesser (Lehigh University, Bethlehem, USA: 'Space and time adaptivity in the numerical integration of partial differential equations' , P. Zegeling (Utrecht University, The Netherlands): 'An adaptive grid method based on smoothed equidistribution and its application to PDEs with higher-order derivatives'. People interested to give a 20 minutes talk are invited to send title and abstract before 15 November by mail or e-mail to my address below. There is space only for a limited number of speeches. People interested to attend are invited to send me a word of subscription too, before 15 November. I hope to have a complete programme a little before 30 November. Hope to see you all!
