Abelianisation of orthogonal groups and the fundamental group of modular varieties

V. Gritsenko, K. Hulek, G. K. Sankaran

We study the commutator subgroup of integral orthogonal groups belonging to indefinite quadratic forms. We show that the index of this commutator is 2 for many groups that occur in…
