algebra, the center of a group G is the set of elements that commute with every element of G. It is denoted Z(G), from German Zentrum, meaning center. In set-builder...

In abstract algebra, group theory studies the algebraic structures known as groups. The concept of a group is central to abstract algebra: other well-known...

finite group is the number of its elements. If a group is not finite, one says that its order is infinite. The order of an element of a group (also called...

Compact groups have a well-understood theory, in relation to group actions and representation theory. In the following we will assume all groups are Hausdorff...
