One of the less obvious but truly fundamental realizations in group theory is the importance of the 'parabolic subgroups' of a linear algebraic group. For the alternating group Alt_n, we have a quasipolylogarithmic diameter bound (Helfgott-Seress 2014), but it does not rest on a product theorem. Proposition 2.7.

There are other algebraic groups, but Chevalley's structure theorem asserts that every algebraic group is an extension of an abelian variety by a linear algebraic group. There are plenty of groups with trivial or finite centre, hence zero dimensional. Show activity on this post. With around 20 members, we are one of the largest such groups in the world. The mainstream point of view in much of the literature on linear algebraic groups is that such an object is a literal group, a set of points, along with a structure identifying it with the points valued in some field, of a variety defined over a possibly smaller field.
