In group theory, a branch of abstract algebra, a **serial subgroup** refers to certain kinds of normal subgroups within a group. Specifically, a subgroup \\( H \\) of a group \\( G \\) is termed a serial subgroup if it can be expressed in a specific way in relation to the entire group \\( G \\) and to other subgroups.
