Timeline

1980

In 1980, Lusztig suggested a character formula for simple modules of reductive groups over fields of finite characteristic p.

1981

Geordie Williamson (born 1981 in Bowral, Australia) is an Australian mathematician at the University of Sydney.

With Ben Elias, he gave a new proof and a simplification of the theory of the Kazhdan–Lusztig conjectures (previously proved in 1981 by both Beilinson–Bernstein and Brylinski–Kashiwara).

For this purpose, they built on works by Wolfgang Soergel and developed a purely algebraic Hodge theory of Soergel bimodules about polynomial rings, In this context, they also succeeded in proving the long-standing positive presumption of positivity for the coefficients of the Kazhdan–Lusztig polynomials for Coxeter groups.

For Weyl groups (special Coxeter groups, which are connected to Lie groups), David Kazhdan and George Lusztig succeeded in doing so by identifying the polynomials with certain invariants (local intersection cohomology) of Schubert varieties.

Elias and Williamson were able to follow this path of proof also for more general groups of reflection (Coxeter groups), although there is no geometrical interpretation in contrast to the case of the Weyl groups.

He is also known for several counterexamples.

1990

He also found counterexamples to a 1990 conjecture of Gordon James on symmetric groups.

His work also provided new perspectives on the respective conjectures.

In 2023 he was awarded an Australian Laureate Fellowship to further his research into fundamental symmetries.

1994

The conjecture was proved in 1994-95 by a combination of three papers, one by Henning Haahr Andersen, Jens Carsten Jantzen, and Wolfgang Soergel, one by David Kazhdan and George Lusztig and one by Masaki Kashiwara and Toshiyuki Tanisaki for sufficiently large group-specific characteristics (without explicit bound) and later by Peter Fiebig for a very high explicitly stated bound.

Williamson found several infinite families of counterexamples to the generally suspected validity limits of Lusztig's conjecture.

1999

Educated at Chevalier College, Williamson graduated in 1999 with a UAI of 99.45.

2003

He studied at the University of Sydney and graduated with a Bachelor's degree in 2003 and then at the Albert-Ludwigs University of Freiburg, where he received his doctorate in 2008 under the supervision of Wolfgang Soergel.

2010

Williamson is the brother of the late James Williamson, a World Solo 24-hour mountain bike champion who died while competing in South Africa in 2010.

2011

After his PhD, Williamson was a post-doctoral researcher at the University of Oxford, based at St. Peter's College, Oxford and from 2011 until 2016 he was at the Max Planck Institute for Mathematics.

Williamson deals with a geometric representation of group theory.

2016

In 2016, he received the Chevalley Prize of the American Mathematical Society and the Clay Research Award.

He is an invited speaker at the European Congress of Mathematicians in Berlin 2016 (Shadows of Hodge theory in representation theory).

In 2016 he was awarded the EMS Prize, for 2017 he was awarded the New Horizons in Mathematics Prize.

2018

He became the youngest living Fellow of the Royal Society when he was elected in 2018 at the age of 36.

In 2018, he was plenary speaker at the International Congress of Mathematicians in Rio de Janeiro and was elected a Fellow of the Royal Society (FRS) and the Australian Academy of Science.

Williamson was awarded the 2018 Australian Mathematical Society Medal and the NSW Premier's Prizes for Science & Engineering: Excellence in Mathematics, Earth Sciences, Chemistry or Physics in 2022.
