Algebras with discrete spectrum
In this and the next three chapters, we will look at a variety of examples. Basic algebras include affl, Heisenberg algebra (3-dimensional), finite-difference algebra, sl(2),e2, and a particular two-step nilpotent algebra that we call the ‘ABCD’ algebra (why — to be explained). And then some examples of higher-dimensional algebras.
