15:00 - 16:00
Organisers:
- Ana F. Loureiro (University of Kent)
- Thomas Bothner (University of Bristol)
- Adri Olde Daalhuis (University of Edinburgh)
- Walter Van Assche (KU Leuven, Belgium)
- Jani Virtanen (University of Reading)
The seminars occur every two weeks, on a Monday, 15:00-16:00 BST, beginning Monday 15 February.
Each seminar we will present a seminar on the topics of orthogonal polynomials and special functions, operator theory and their remarkable applications to other fields of mathematics including analytic number theory, random matrix theory, numerical and computational methods and mathematical physics. The focus of discussion will be on the fruitful interactions between numerical analysis, approximation theory, operator theory, spectral methods, combinatorics and the modern theory of orthogonal polynomials and special functions.
The series is organised by the OPSFOTA research network group funded by LMS. Due to the funding limitations it was restricted to researchers that are based in geographically close institutions: in the UK, University of Kent, University of Reading, King’s College London, Imperial College, University of Sussex, University College London and elsewhere in Europe KU Leuven (Belgium), Radboud Universiteit (the Netherlands) and Université Lille (France). The current situation has given the us the opportunity to open the seminar series to anyone who would like to participate.
To register to attend the seminar please complete this form.
Registration will close at 12.00 on the day of the seminar. The meetings will be held using Zoom and joining details will be sent after 12.00 on the day of the seminar.
