The Three Faces of $U (3)$

J. LaChapelle

$U (n)$ is a semi-direct product group that is characterized by non-trivial homomorphisms mapping $U (1)$ into the automorphism group of $S U (n)$ . For $U (3)$ , there are three non-triv…

Apparent Geometry from the Quantum Mechanics of $S p (8, C)$

J. LaChapelle

Restricting attention to kinematics, we develop the $C^{*}$ -algebraic quantum mechanics of $S p (8, C)$ . The non-compact group does double duty: it furnishes the quantum Hil…

A non-Standard Standard Model

J. LaChapelle

We examine the Standard Model under the electroweak symmetry group $U_{E W} (2)$ subject to the Lie algebra condition $\mathfrak{u}_{EW}(2)\not\cong \mathfrak{su}_{I}(2)\oplus \mathf…
