Extract
In a recent series of papers [3,4,5], H. Zassenhaus considered the structure of those linear transformations T on real 4-space, R4, into itself that preserve the quadratic form . That is,
1.1
Define a function ϕ on R4 to the space M 2 of 2-square matrices over the complex numbers as follows:
1.2
Let G2 be the vector space of matrices generated by all real linear combinations of
