Abstract We formulate a geometric measurement theory of dynamical classical systems possessing both continuous and discrete degrees of freedom. The approach is covariant with respect to choices of clocks and naturally incorporates laboratories. The l

Distant and isolated, remote heritage sites are inherently difficult to protect. In this paper, examination of the Cold War-era Distant Early Warning (DEW) Line of radar installations in the Canadian arctic, built as a defense system for North Americ

We present a generally covariant approach to quantum mechanics in which generalized positions, momenta and time variables are treated as coordinates on a fundamental “phase-spacetime”. We show that this covariant starting point makes quantization

Lichnerowicz's algebra of differential geometric operators acting on symmetric tensors can be obtained from generalized geodesic motion of an observer carrying a complex tangent vector. This relation is based upon quantizing the classical evolution e

We develop an approach to the conformal geometry of embedded hyper- surfaces by treating them as conformal infinities of conformally compact manifolds. This involves the Loewner-Nirenberg-type problem of finding on the interior a metric that is both

The invariant theory for conformal hypersurfaces is studied by treating these as the conformal infinity of a conformally compact manifold. Recently it has been shown how, given a conformal hypersurface embedding, a distinguished ambient metric is fou

We develop an efficient calculus for varying hypersurface embeddings based on variations of hypersurface defining functions. This is used to show that the functional gradient of a new Willmore-like, conformal hypersurface energy agrees exactly with t

The problem of computing quantum mechanical propagators can be recast as a computation of a Wilson line operator for parallel transport by a flat connection acting on a vector bundle of wave functions. In this picture, the base manifold is an odd-dim

In the United States, it has long been customary to suggest that we are teaching actors a “toolbox.” While true and always meant with the best intent, it also may be a bit of a cop-out. Give me a t...
