In order to study random walks on reductive groups over local fields, we collect in this chapter a few notations and facts about these groups: the definition of the flag variety, the Cartan projection and the Iwasawa cocycle. Those extend the notations and facts for semisimple real Lie groups that we collected in Sect. 6.7.

WebSince Busemann functions are invariant by isometries, so are horospheres, and they pass to the quotient T1M. We introduce the notation ˘(x;y) := b V(y;˘)(x); that we will use later. This quantity is equal to the distance between the horocycles centered at ˘passing through xand y. It is called a Busemann cocycle and it depends hunger pain
