orthogonal group
noun1
Group theory, Mathematics, Sciences For given n and field F (especially where F is the real numbers), the group of n × n orthogonal matrices with elements in F, where the group operation is matrix multiplication.
- The symbol O^ε(n,q) for orthogonal groups has been well established in finite group theory as and, throughout the mathematics community, O(n, K) stands for an orthogonal group when K is the real or complex field.1998, Robert L. Griess, Jr., Twelve Sporadic Groups, Springer, page 4:
- Theorem 7.4. Let n ≥ 1. For odd primes p#92;not#92;equiv#92;pm 1#92;pmod#123;24#125; the odd-dimensional orthogonal groups O#95;#123;2n#43;1#125;(p) possess GA-realizations over #92;mathbb#123;Q#125;.1999, Gunter Malle, B.H. Matzat, Inverse Galois Theory, Springer, page 146:
