… spacetime and make sense in curved spacetime. We will take as a basic principle that
the quantum field theory should satisfy suitable microlocal spectral conditions. We will give …

… From this we may understand that time inside the star runs slow relative to time outside the
star. To be more specific, consider the following scenario. Let an observer far outside the star …

… , and all the other collaborators and professional colleagues who have helped build our
current understanding of these aspects of quantum field theory in curved space-time. …

… We discuss the special problem of conservation of energy in a curved spacetime, which is
less trivial than it seems. We end by using the concepts of this chapter to show the effect of …

This review is concerned with the motion of a point scalar charge, a point electric charge, and
a point mass in a specified background spacetime. In each of the three cases the particle …

… substantive adjustment of our understanding of time and space … spacetime, and objects
respond to this curvature by following the straightest possible paths within that curved spacetime…

… A fundamental task — I might even say the main problem — in developing a quantum field
theory in curve spacetime is to understand the stress tensor. The stress tensor, like any current…

… In this article, we examine the generalized vortical formalism in curved space–time for the
purpose of drawing attention to the robust toolbox it offers for understanding plasma …
