In the 70s, Deligne and Lusztig studied representations of finite groups of Lie type by realizing them in the cohomology of suitable subvarieties of flag varieties. Affine Deligne-Lusztig varieties are a generalization to subvarieties of affine flag varieties. They occur naturally in the study of the reduction modulo p of Shimura varieties. In this talk I will explain the definition of affine Deligne-Lusztig varieties and give a survey of recent results on their geometry.
