Representations of SO(4,2;R) are constructed using 4 x 4 and 2 x 2 matrices with elements in H' ⊗ C . Using 2 x 2 matrix representations of C and H', the 4 x 4 representation is interpreted in terms of 16 x 16 real matri ...
The existence of generalized symmetries of Maxwell's equations in G¨odel's Universe
is investigated. It is shown that their existence is in turn tied to the existence of certain
spinorial objects called Killing spinors ...
A fundamental question related to any Lie algebra is to know its subalgebras. This is
particularly true in the case of E6, an algebra which seems just large enough to contain the algebras which describe the fundamental ...
