Linear Descent in Spherical Tits-Buildings with Applications to Rank 1 Groups, Density Theorems in Chevalley Groups, and Finite Geometry. Ghent University
In mathematics the automorphism group measures the amount of symmetry of any object. Sometimes an efficient way to study an object is to study its group. Group theory has become a very important area in mathematics. Reciprocally, an efficient way to study a group is to study a suitable object on which it acts. Groups of Lie type are important groups in mathematics, and Jacques Tits produced abstract geometries on which they act in a natural ...
