Gravitational kinks in two spacetime dimensions

The properties of gravitational kinks are studied within some simple models of two dimensional gravity. In spacetimes of cylindrical topology we prove the existence of kinks of constant curvature with arbitrary kink numbers. In R R spacetimes m = 1 kink solutions of the equation R = 0 are found, whereas jmj > 1 at kinks are proved not to exist. We give a detailed analysis of the behaviour of gr...

0 Gravity in Two Spacetime Dimensions

IJEE Soapbox: A World free of pArAsites And vectors: Would it be heAven, or Would it be hell?

This is of course impossible, but Gould’s thought experiment is a useful conceptual exercise which brings out key issues of determinism versus randomness in history. More broadly, it can be illuminating to ponder all kinds of implausible and radical scenarios, in effect bracketing the real world with visions of possible worlds. What would our world now be like if, at some time in the past, a ma...

Classical Physics of Thermal Scalar Radiation in Two Spacetime Dimensions

Abstract Thermal scalar radiation in two spacetime dimensions is treated within relativistic classical physics. Part I involves an inertial frame where are given the analogues both of Boltzmann’s derivation of the Stefan-Boltzmann law and also Wien’s derivation of the displacement theorem using the σltU−1-scaling of relativistic radiation theory. Next the spectrum of classical scalar zeropoint ...
