Leiden: Talk by Manjul Bhargava22-1-2010 (friday)
Title: Binary quartic forms and ranks of elliptic curves
Place: Snellius building (Niels Bohrweg 1, Leiden), room 405
We prove a theorem giving the asymptotic number of binary quartic
forms having bounded invariants; this extends, to the quartic case,
the classical results of Gauss and Davenport in the quadratic and
cubic cases respectively. We use this counting result to prove - among
other things - the boundedness of the average rank of elliptic curves
when ordered by their heights.

NWO Call for Tenure Track positions22-7-2016
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 25-5-2016
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. Read more in Terence Tao's blog about these developments.
Harry Buhrman lectures on quantum computing in Universiteit van Nederland21-1-2015
Starting 12 January 2015, the Universiteit van Nederland publishes five public lectures by Harry Buhrman, head of the research group quantum computing at CWI. The series of lectures features the do's and don'ts of the computer of the future. From Monday through Friday, a new lecture will be available on the site of the Universiteit van Nederland each day.
