A basis B of a vector space V over a field F (such as the real numbers R or the complex numbers C) is a linearly independent subset of V that spans V.This means that a subset B of V is a basis if it satisfies the two following conditions: . Firstly, the projective linear group PGL(2,K) is sharply 3-transitive for any two ordered triples of distinct points, there is a unique map that takes one triple to the other, just as for Mbius transforms, and by the same algebraic proof (essentially dimension counting, as the group is 3-dimensional).Thus any map that fixes at least 3 points is the identity. The center of SU(n) is isomorphic to the cyclic group /, and is composed of the diagonal Basis (linear algebra representation Given the above, for every point in this ball there is a rotation, with axis through the point and the origin, and rotation angle equal to the distance of the point from the origin. In mathematics, the unitary group of degree n, denoted U(n), is the group of n n unitary matrices, with the group operation of matrix multiplication.The unitary group is a subgroup of the general linear group GL(n, C). the set of all bijective linear transformations V V, together with functional composition as group operation.If V has finite dimension n, then GL(V) and GL(n, F) are isomorphic. The definitions and notations used for TaitBryan angles are similar to those described above for proper Euler angles (geometrical definition, intrinsic rotation definition, extrinsic rotation definition).The only difference is that TaitBryan angles represent rotations about three distinct axes (e.g. Mbius transformation - Wikipedia In quantum mechanics and computing, the Bloch sphere is a geometrical representation of the pure state space of a two-level quantum mechanical system (), named after the physicist Felix Bloch..

Lorentz group A basis B of a vector space V over a field F (such as the real numbers R or the complex numbers C) is a linearly independent subset of V that spans V.This means that a subset B of V is a basis if it satisfies the two following conditions: .

All three of the Pauli matrices can be compacted into a single expression: = (+) where the solution to i 2 = -1 is the "imaginary unit", and jk is the Kronecker delta, which equals +1 if j = k and 0 otherwise.
