So to get from ( , ) to ( , ) we have to apply an invertible, norm-reserving linear operation, that is, an unitary operation. The SU ( n) groups find wide application in the Standard Model of particle physics, especially SU (2) in the electroweak interaction and SU (3) in QCD. The special linear group $\SL(n,\R)$ is a subgroup. Proof 2. Geometry of the Special Unitary Group The elements of SU2 are the unitary 2 2 matrices with determinant 1. The inverse of any such matrix exists by definition, and of course $\mathbb{1}$ is unitary. special unitary group () 1 1 (,) . (q) and projective special unitary group PSU. Define special-unitary-group. The special unitary group is the set of Unitary Matrices with Determinant (having independent parameters). Note A unitary group of entities is united by more than 50 percent common ownership. Properties. The subgroup of the unitary group consisting of matrices of determinant 1 is called the special unitary group and denoted SU (n, q) or SU (n, q2). spect to which the group operations are continuous. The shortest answer might be: It is the group of complex matrices, which are unitary of determinant : . In mathematics, the projective unitary group PU(n) is the quotient of the unitary group U(n) . Generators of the S U ( 2) group. It is also called the unitary unimodular group and is a Lie group . The special unitary group S U ( n) is the Lie group of n n unitary matrices with determinant 1. Note For a finite field the matrices that preserve a sesquilinear form over F q live over F q 2. U ^ = exp ( i i . (q) are the groups obtained from GU. This group can be considered as a sub variety of the affine space M_ {n\times n} (k) of square matrices of size n carved out by the equations saying that the determinant of a matrix is 1. A unitary matrix U is one that satisfies. Contents. As a compact classical group, U (n) is the group that preserves the standard inner product on Cn. (More general unitary matrices may have complex determinants with absolute value 1, rather than real 1 in the special case.) , .

The special unitary group SU. For non-Abelian unitary groups, the number of phase angles (parameters) is determined by the formula N a = n 2 - 1, where n is the dimension of the internal space, e.g., N a = 3 for n = 2 in SU (2). Equivalently, we may consider four linearly independent 2 2 matrices which represent the generators of the transformation. This generates one random matrix from U(3). On the groups with the same orders of Sylow normalizers as the finite projective special unitary group. Furthermore, it is a subgroup of the unitary group and the special linear group.
