WebIn mathematics, Borel–de Siebenthal theory describes the closed connected subgroups of a compact Lie group that have maximal rank, i.e. contain a maximal torus. It is named after the Swiss mathematicians Armand Borel and Jean de Siebenthal who developed the theory in … • Every product of (arbitrarily many) profinite groups is profinite; the topology arising from the profiniteness agrees with the product topology. The inverse limit of an inverse system of profinite groups with continuous transition maps is profinite and the inverse limit functor is exact on the category of profinite groups. Further, being profinite is an extension property. • Every closed subgroup of a profinite group is itself profinite; the topology arising from the profiniteness agree… WebH ⊂G is a closed subgroup, then H is proﬁnite. Similarly, if N ⊂G is a closed normal subgroup, then G/N is proﬁnite with the quotient topology.

WebWe write that the subgroup is generated by {x,y,z}. But this subgroup includes x-1 and y 3 (z-1) 6 and other such products that involve the inverses of x,y,z, because that's necessary for it to be a (sub)group at all..

Let N ( T) and N ( H) denote the normalizers of T and H respectively. Show that if N ( T) ⊂ H then N ( H) = H. I was able to show that N ( H) / H should be finite. But showing this only used the fact that T ⊂ H.
