What is Core (group theory)?

Buttressed core is a structural system for high buildings, consisting of a hexagonal core reinforced by three buttresses that form a Y shape.

The membrane theory of shells, or membrane theory for short, describes the mechanical properties of shells when twisting and bending moments are small enough to be negligible. The spectacular simplification...

In mathematics, computational group theory is the study ofgroups by means of computers. It is concernedwith designing and analysing algorithms anddata structures to compute information about groups. The subjecthas attracted...

In mathematics, in the field of group theory, the perfect core of a group is its largest perfect subgroup. Its existence is guaranteed by the fact that the subgroup generated...

In mathematics, the representation theory of the symmetric group is a particular case of the representation theory of finite groups, for which a concrete and detailed theory can be obtained....

In mathematical group theory, the automorphism group of a free group is a discrete group of automorphisms of a free group. The quotient by the inner automorphisms is the outer...

A core router is a router designed to operate in the Internet backbone, or core. To fulfill this role, a router must be able to support multiple telecommunications interfaces of...

Many first principles in quantum field theory are explained, or get further insight, in string theory.

In the petroleum industry, special core analysis, often abbreviated SCAL or SPCAN, is a laboratory procedure for conducting flow experiments on core plugs taken from a petroleum reservoir. Special core...
