Ultrametric logarithm laws i

J. S. Athreya, Anish Ghosh, Amritanshu Prasad

Research output: Contribution to journalArticlepeer-review


We announce ultrametric analogues of the results of KleinbockMargulis for shrinking target properties of semisimple group actions on symmetric spaces. The main applications are S-arithmetic Diophantine approximation results and logarithm laws for buildings, generalizing the work of Hersonsky-Paulin on trees.
