Did a Decadent Metre Exist at the ,?,mensional Euclidean group. The advantage of the first approach (Section 5.2) is that the representation theory of all three Lie algebras can be obtained in a unified manner. We are interested only in so(4) so our final results will be presented only for this case. A general discussion of so(.) and so(.) is given in Appendix B.

In fact the first 5 orders were first calculated only in 1976 by Galindo and Pascual [GA76] using the method of Dalgarno and Lewis [DA55], [DA56a], [SC68].

Michael S. Okundamiya,Samuel T. Waraown how the infinitesimal group transformations corresponding to one-parameter subgroups give rise to the generators of the associated Lie algebra. Also we discuss the special unitary group SU(2), which is important for spin in quantum mechanics, and show its connection with SO(3).

Representations and Realizations of so(2,1), a spectrum-generating algebra in the sense that energy formulas such as the Bohr formula are all obtained in a unified and purely algebraic manner without resorting to the series solutions of second order radial differential equations.
