 Special unitary group

The Special Unitary Group, denoted as \( \text{SU}(n) \), is a significant mathematical structure in the field of group theory, particularly in the study of symmetries and quantum mechanics.

The complex analogue of the special orthogonal group, i.e. the subgroup of the unitary group with determinant equals exactly 1 instead of an arbitrary complex number with absolute value equal 1 as is the case for the unitary group.
