This is a short survey of the progress on the congruence subgroup problem since the sixties when the first major results on the integral unimodular groups appeared. It is aimed at the non-specialists and avoids technical details. 
Centrality of the congruence subgroup kernel of higher rank non-uniform arithmetic groups
We give a simple proof of the centrality of the congruence subgroup kernel in the higher rank isotropic case.
Generations for Arithmetic Groups
We prove that any noncocompact irreducible lattice in a higher rank real semi-simple Lie group contains a subgroup of finite index which is generated by three elements.
Generators for Arithmetic Groups
We prove that any non-cocompact irreducible lattice in a higher rank semi-simple Lie group contains a subgroup of finite index, which has three generators.
On the congruence subgroup problem for branch groups
We answer a question of Bartholdi, Siegenthaler and Zalesskii, showing that the congruence subgroup problem for branch groups is independent of the branch action on a tree. We prove that theExpand
Some aspects of profinite group theory
A survey of recent results about profinite groups, and results about infinite and finite groups where the theory of profinite groups plays a leading role.
Congruence subgroups of braid groups
These notes are based on a mini-course given at CIRM in February 2018 as part of the workshop Winter Braids VIII.
The representation theory of SLn(Z)
We give a fairly complete description of the finite-dimensional characteristic 0 representation theory of SLn(Z) for n ≥ 3, following work of Margulis and Lubotzky.
Arithmetic Groups Have Rational Representation Growth
Let G be an arithmetic lattice in a semisimple algebraic group over a number field. We show that if G has the congruence subgroup property, then the number of n-dimensional irreducibleExpand
Introduction to Shimura Varieties
This is an introduction to the theory of Shimura varieties, or, in other words, to the arithmetic theory of automorphic functions and holomorphic automorphic forms.
Profinite invariants of arithmetic groups
Abstract We prove that the sign of the Euler characteristic of arithmetic groups with the congruence subgroup property is determined by the profinite completion. In contrast, we construct examplesExpand

ADDENDUM TO THE PAPER "THE PROBLEM OF STRONG APPROXIMATION AND THE KNESER-TITS CONJECTURE FOR ALGEBRAIC GROUPS"
This paper contains several additional observations which serve to revise and further unify the proof of the approximation theorem.
The Congruence Subgroup Problem
The results I shall describe represent work initiated by John MILNOR and myself [I], and concluded in collaboration with J.-P. Serre [2]. Serre’s discovery that our problem is very closely related toExpand

We show that any two maximal disjoint unipotent subgroups of an irreducible non-cocompact lattice in a Lie group of rank atleast two generates a lattice. The proof uses techniques of the solution ofExpand

That the factor space of a semisimple Lie group by an arithmetic subgroup has finite volume with respect to Haar measure is well known. In this paper we study results related to the converse of thisExpand
