The exponential map of GL(N)
Alexander Laufer
A finite expansion of the exponential map for a matrix is presented. The method uses the Cayley-Hamilton theorem for writing the higher matrix powers in terms of the fi…

The exponential map for the unitary group SU(2,2)
A. O. Barut, J. R. Zeni, A. J. Laufer
In this article we extend our previous results for the orthogonal group, , to its homomorphic group . Here we present a closed, finite formula for the exponential…

The Exponential Map for the Conformal Group 0(2,4)
A. O. Barut, J. R. Zeni, A. J. Laufer
We present a general method to obtain a closed, finite formula for the exponential map from the Lie algebra to the Lie group, for the defining representation of the orthogonal grou…
