April 7, 1998 32nd Mathematical Colloquium: talk given by Jennifer Chayes ("Birth of the Infinite Cluster: Finite-size Scaling in Percolation").

April 20-24, 1998 Spring School of Combinatorics, Borova Lada. Traditional meeting of students and their teachers.

May 1998 Short term visitors:

  • S. Brandt (Berlin)

June 8-10, 1998 Joint DIMACS-DIMATIA workshop From Erdos to Algorithms (shortly e2a), DIMACS, New Jersey. Organized by Joel Spencer (DIMACS) and Jaroslav Nesetril (DIMATIA). The workshop was intended not only to remember the memory of Paul Erdos, but also to illustrate the influence of P. Erdos's mathematics on modern branches of mathematics and computer science.
Abstracts were published in KAM-DIMATIA Series.

July 6-11, 1998 Fifth Czech-Slovak International Symposium on Combinatorics, Graph Theory, Algorithms and Applications, Suchdol Campus of Agricultural University, Prague. The Symposium was organized by DIMATIA in cooperation with the majority of Czech and Slovak universities and academic institutions as the fifth in a series of symposia which started with 1963 Smolenice meeting and continued in 1974, 1982 (Prague) and 1990 (Prachatice). This year there were more than 200 participants from all over the world. The scientific program, divided into five sections, covered almost all aspects of contemporary combinatorics and graph theory from both the theoretical and applied viewpoints.
Proceedings of the symposium will be published by Elsevier North-Holland as a special volumes of Discrete Mathematics. Abstracts were published in KAM-DIMATIA Series.

August 1998 Joint DIMACS-DIMATIA workshop On Computational Geometry, DIMATIA, Prague. Workshop was organized by Jiri Matousek and Pavel Valtr. Several international leaders participated (R. Shamir (Tel Aviv), B. Chazelle (Princeton)).

October 1998 Short term visitors:

  • P. Hell (Burnaby)

October 1998 DIMATIA was jointly with LaBRI, Bordeaux, Rheinische Friedrich-Wilhelms-Universitat Bonn and Humboldt Universitat, Berlin awarded an EU grant in terms of IP-Socrates Program to support The International Spring School of Combinatorics '99.

November 1998 Short term visitors:
