Embedded Space-Time and Particle Symmetries

Reviews of Modern Physics, 1965
The bootstrap yields the strong-interactions symmetry provided the hadron currents participating in nonstrong interactions are first fed into it; the alternative course, in which the bootstrap is required to generate the entire symmetry uniquely, with no a priori information from the nonstrong interactions, seems to lie beyond the present techniques ...

Internal-Symmetry Groups and Curved Space-Time

Physical Review, 1965
Some theorems are proved which exhibit the impossibility of constructing nontrivial products of the 3+2 de Sitter group with internal-symmetry groups (under physically reasonable assumptions). It is shown that either mass degeneracy, $[{E}_{\ensuremath{\alpha}},{P}_{\ensuremath{\mu}}]=0$, or simultaneous measurement of internal quantum numbers and ...

Macroscopic symmetry in space-time

Reports on Progress in Physics, 1963
Magnetic and non-magnetic crystallographic point groups may be distinguished by the different relations in which they stand to the time-inversion or anti-identity operator R. The 32 point groups of classical crystallography G may be used to generate both magnetic and non-magnetic groups.
