CWI Amsterdam: EIDMA/DIAMANT minicourse by Pablo Parrilo

*31-5-2010 - 4-6-2010*Lecturer: Pablo Parrilo.

In due time, see this page for details.

Title: Algebraic Optimization and Semidefinite Programming.

Abstract: This minicourse will focus on theoretical and computational techniques for

optimization problems with algebraic structure (in particular, those

involving polynomial equations and inequalities), emphasizing the

connections with techniques based on semidefinite programming (SDP).

The course will develop in a parallel fashion several algebraic and

numerical approaches to polynomial systems, with a view towards methods

that simultaneously incorporate both elements. We will study both the

complex and real cases, developing techniques of general applicability,

and stressing convexity-based ideas, complexity results, and efficient

implementations. We will use examples from several applied math and

engineering areas, including systems and control, geometric theorem

proving, and classical and quantum information theory.

Among the topics covered we will have: semidefinite relaxations, sum of

squares representations, hyperbolic polynomials, SDP representability of

convex sets, complex and real Nullstellensatz, convex algebraic geometry,

sparsity and rank minimization problems, etc.

**NWO Call for Tenure Track positions***22-7-2016*
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.
