An ICTP Virtual Meeting
The aim of the course is to provide training in the foundations of commutative algebra and algebraic geometry in prime characteristic and to present some of the exciting recent developments. The local theory of prime characteristic singularities is a beautiful and historically important subject. Singularities which are defined in terms of the behaviour of the Frobenius endomorphism have been labeled “F-singularities”. The course gives an introduction on the most prominent F-singularity classes that emerged from Hochster–Huneke’s tight closure theory. Since its introduction in the late 1980s, it has had a dramatic effect on the field of commutative algebra. Tight closure gives unified proofs and strong generalisations of many major theorems in commutative algebra, as well stimulated recent proofs of longstanding conjectures.

Lectures. There will be 3 lectures and a tutorial on each topic each week. The speakers will provide detailed typed notes of their lectures on the day they finish their lectures. These notes will contain exercises which the participants should try to solve and submit to the tutorial instructor before 12 pm GMT on Fridays.
Tutorials. The tutorial on each topic will be held a week after the lectures are delivered. The tutorial instructor will present solutions to problems assigned by the Lecturer that are received from the participants and discuss some material covered during the lectures. Grades will be assigned to the solutions.
Registration: There is no registration fee.
