Bounds for the orders of the finite subgroups of G(k)
arXiv:1011.0346
Abstract
If k is a commutative field and G a reductive (connected) algebraic group over k, we give bounds for the orders of the finite subgroups of G(k); these bounds depends on the type of G and on the Galois groups of the cyclotomic extensions of k.
