1. Subgroup

   In group theory, a branch of mathematics, given a group G under a binary operation ∗, a subset H of G is called a subgroup of G if H also forms a group under the operation ∗. More precisely, H is a subgroup of G if the restriction of ∗ to H × H is a group operation on H. This is often denoted H ≤ G, read as "H is a subgroup of G". The trivial subgroup of any group is the subgroup {e} consisting of just the identity element.A proper subgroup of a group G is a subgroup H which is a proper subset of G (that is, H ≠ G). This is often represented notationally by H < G, read as "H is a proper subgroup of G". Some authors also exclude the trivial group from being proper (that is, H ≠ {e}).If H is a subgroup of G, then G is sometimes called an overgroup of H. The same definitions apply more generally when G is an arbitrary semigroup, but this article will only deal with subgroups of groups.

1. subgroup

   A subgroup is a subset of a group that is itself a group under the operation of the larger group. The elements of a subgroup share a specific property, obey the group's laws, and the subgroup contains the group's identity element as well as the inverse of each element in the subgroup. In essence, it's a smaller group within a larger group that maintains the properties of group structure such as closure, associativity, identity and inverses.

1. Subgroup

   In mathematics, given a group G under a binary operation *, a subset H of G is called a subgroup of G if H also forms a group under the operation *. More precisely, H is a subgroup of G if the restriction of * to H x H is a group operation on H. This is usually represented notationally by H ≤ G, read as "H is a subgroup of G". A proper subgroup of a group G is a subgroup H which is a proper subset of G. The trivial subgroup of any group is the subgroup {e} consisting of just the identity element. If H is a subgroup of G, then G is sometimes called an overgroup of H. The same definitions apply more generally when G is an arbitrary semigroup, but this article will only deal with subgroups of groups. The group G is sometimes denoted by the ordered pair, usually to emphasize the operation * when G carries multiple algebraic or other structures. This article will write ab for a*b, as is usual.

Examples of subgroup in a Sentence

1. Alessio Fasano:

   There is a possibility that some groups of individuals with other chronic inflammatory conditions, including autoimmune diseases like diabetes or multiple sclerosis, of course autism ... and schizophrenia ... there could be a subgroup of these individuals that could benefit from embracing a gluten-free diet, for schizophrenia, for example, we're talking about 20% or 25%. That's not a trivial number.

2. Barbara Carvalho:

   Those previous numbers cited were not of a full survey of Latinos but the result from the smaller subgroup that make up a survey of Americans. The margin of error was wide and the results should not be taken to conclude what would have been found among this very diverse group had we done a larger study of only Hispanic and Latino Americans.

3. Courtney Kennedy:

   There are a number of subgroup estimates that bounce around from poll to poll, as a result, the results are sometimes incoherent when looking across polls. This variation across polls is testament to the tremendous variation in the methods used to conduct polling these days.

4. Courtney Kennedy:

   I think poll watchers would do well to accept that the field is in an era of transition, and one consequence of that is a frustrating amount of noise in subgroup estimates.
