Opportunity for a PhD position: 
There is a PhD position available for a project funded by the Dutch Scientific Council (NWO), entitled The Synergy between Semidefinite Programming and Approximation Theory.
This concerns a 4-year paid PhD position in the Department of Econometrics and Operations Research. 

A master’s degree in (Applied) Mathematics, Operations Research, or a related discipline is required, and specialized knowledge of Approximation Theory and/or Semidefinite Programming would be ideal. More generally, a solid background in numerical analysis and mathematical optimization is necessary for this project.

The envisaged starting date for the position is September 1st, 2024, but a later date is negotiable. Applications will be dealt with on a first-come-first-serve basis until the position is filled. To get an idea of the topic of the proposal, potential candidates are encouraged to look at the preprints https://arxiv.org/abs/2404.04190, https://arxiv.org/abs/2405.19219 and https://arxiv.org/abs/2405.10438 before applying.

Please be aware that the PhD program in Business requires that you follow PhD courses in the first year. The courseload amounts to 36 ECTS, which is the equivalent for 6 full courses. The course program is composed by your supervisor and PhD program coordinator. 
 
PhD position
When you will be hired as a PhD candidate, you will be enrolled as a PhD candidate in the world-class PhD program of CentER Graduate School for Economics and Business. PhD candidates are supervised by two faculty advisors, of which at least one is senior.

Depending on the assessment of previous coursework, you may need to take some extra courses to complement skills.
