WebbFor a simply-connected group G, we can now give a unique definition of U(g) for all g, by using (3). Setting U(1G) = 1, define U(g 0) by choosing any path from the identity 1G to g 0 and demanding that U(g) changes smoothly along it. The values along the path are unique (by the determinant condition and continuity) but the end result U(g 0 ... sidewinder electric stepsWebbThis group has two components, with the component of the identity SO(n;R), the orthogonal matrices of determinant 1.
