T.A. Springer Visiting Professorship
In 2024, the Utrecht Geometry Centre established an annual visiting professorship, named after T.A. Springer (1926 – 2011), who served as professor of mathematics at Utrecht University from 1959 to 1991. Professor Springer is well-known for his work in algebraic groups, Hecke algebras and complex reflection groups. He introduced two important notions in representation theory which became subsequently known as the Springer representation and the Springer resolution.
The aim of the visiting professorship is to stimulate influx of new mathematical ideas into the UGC community. Occupants of the chair are selected for their distinguished roles in contributing to new developments in international mathematical research, in areas of interest to the UGC community. Chair holders typically work at our institute for a period of one month, and are expected to contribute to the scientific activities of the UGC by interacting with its members through seminars, mini-courses, or other forms of collaboration.
2025/2026 Springer Chair: M. Reineke
Prof. Markus Reineke is a professor of mathematics at Ruhr University Bochum. He is a leading expert in representation theory, in particular in the theory of quiver representations and their moduli spaces, with deep connections to algebraic geometry, Lie theory, and mathematical physics. His work has played a central role in the development of Hall algebras, Donaldson–Thomas type invariants, and wall-crossing phenomena, and he has made influential contributions to the interplay between representation theory, geometry, and enumerative invariants arising from moduli problems.
Prof. Markus Reineke will be offering the following:
- A colloquium talk: Noncommutative Hilbert schemes and a Springer resolution.
- A lecture series: Quiver moduli and their geometry.
- A "problem session” in which various interesting and tractable questions on quiver moduli are described.
- A 2-day workshop on February 23 and 24.
