Arjeh Cohen 60


On 27, 28, and 29 May 2009 the DIAMANT/EIDMA Symposium will be held at De Kapellerput, Heeze. This is not an ordinary symposium; we will be celebrating the 60th birthday of Arjeh Cohen, board member of both DIAMANT and EIDMA. The emphasis of the conference will be on the areas of mathematics most prominent in Arjeh's work: Group Theory, Incidence Geometry, Algebra, and Algorithms.

Bruce Cooperstein (UC Santa Cruz)
Willem de Graaf (Trento)
Wilberd van der Kallen (Utrecht)
William Kantor (University of Oregon)

NWO Call for Tenure Track positions

NWO has opened a call for tenure track positions. Proposals for these positions, which include one PhD position for each tenure track position, can be submitted directly to NWO by professors from the 4 mathematics clusters, including Diamant. Diamant professors are warmly encouraged to submit proposals. Read more.

Dion Gijswijt and Jordan Ellenberg independently substantially improve capset bound

A capset in a finite dimensional vector space over the field with 3 elements is a subset that contains no 3-term arithmetic progressions. Dion Gijswijt (TU Delft) and Jordan Ellenberg have independently obtained a bound on the size of a capset that for the first time improves substantially on the trivial bound 3^n.
