The CIMPA Research School on Group Actions in Arithmetic and Geometry will be hosted by Department of Mathematics (Universitas Gadjah Mada, Yogyakarta, Indonesia) on February 17th-28th, 2020. This school can be considered as a continuation of the SEAMS school held at Universitas Gadjah Mada in 2015 ( see: seams-school2015).

The participants in this school will learn relations between symmetries in geometry, analysis, and number theory. In this school, the lecturers will present groups and the natural objects they act on in a variety of arithmetic and geometric contexts. Special emphasis will be given to concrete examples, and moreover practical and computational aspects of groups and their actions will be stressed. The topics to be discussed include finite fields, coding theory, covering spaces, representation theory, modular forms, and Galois theory.
