A Note on the Topology of Space-time in Special Relativity
S. Wickramasekara
We show that a topology can be defined in the four dimensional space-time of special relativity so as to obtain a topological semigroup for time. The Minkowski 4-vector character o…

On Einstein Causality and Time Asymmetry in Quantum Physics
S. Wickramasekara, A. Bohm
A theorem of Hegerfeldt shows that if the spectrum of the Hamiltonian is bounded from below, then the propagation speed of certain probabilities does not have an upper bound. We pr…
