# Abstract Harmonic Analysis on Spacetime.

@article{ElHussein2014AbstractHA, title={Abstract Harmonic Analysis on Spacetime.}, author={Kahar El-Hussein}, journal={arXiv: Mathematical Physics}, year={2014} }

Let G = SL(2,C) be the 2×2 connected complex Lie group and let P = R 4 ⋊SL(2, C) be the Poincare group (space time). In mathemat- ics, the Poincare group (spacetime), named after Henri Poincare, is the group of isometries of Minkowski spacetime, introduced by Hermann Minkowski. It is a non-abelian Lie group with 10 generators. Space- time, in physical science, single concept that recognizes the union of space and time, posited by Albert Einstein in the theories of relativ- ity (1905, 1916). One…
