Topics for the workshop:
The details of the courses are as follows:
Course 1 - Finite Groups of Lie type: This topic would be a natural follow up of the 2019 AIS on Algebraic groups where the theory over algebraically closed fields was considered. This topic intends to expose the participants to the structure of reductive groups defined over a finite field and their representations with emphasis on Deligne-Lusztig theory.
Course 2 - Word maps and linear groups: It was a conjecture of Oystein Ore, from 1951, that every element of a non-abelian finite simple group G is a commutator. After almost 60 years, this conjecture was settled in affirmative in the celebrated paper of Liebeck, O’Brien, Shalev, and Tiep, well-known in the community as LOST. Ore’s conjecture asserts that the function, not a group homomorphism, from G x G to G which sends a pair (g, h) to the element ghg^{-1}h^{-1} is surjective. It was then natural to consider various such maps, called word maps, and investigate their properties.
The theory of word maps on groups and their applications has developed significantly in the past two decades, with emphasis on finite simple groups, infinite linear groups, profinite groups and related objects. Word width was studied, leading to solutions to a question of Serre (by Nikolov and Segal) and the conjecture of Ore, stated above. Probabilistic aspects of word maps were also explored, leading to a probabilistic Tits alternative for linear groups, characterizations of probabilistically nilpotent groups, as well as recent solutions to probabilistic Waring problems. This series of lectures will describe these developments, related results, and tools used in the proofs.
