Lectures on Electric-Magnetic Duality and the Geometric
... The factor i arises because of Riemannian signature of the metric; in Lorenzian signature similar manipulations would produce an identical formula but without i. The above derivation of electric-magnetic duality is valid only when X is topologically trivial. If H 2 (X) 6= 0, we have to insert addit ...

Is the standard Casimir force formula modified by quantum charge fluctuations in the ground state of the metals ? Corrections to the leading asymptotic term ? Make explicit connections with Lifshitz theories Re ...

Topology
... What is topology? • The word topology comes from the Greek topos, "place," and logos, "study” • Topology was known as geometria situs (Latin geometry of place) or analysis situs (Latin analysis of place). • The thing that distinguishes different kinds of geometries is in terms of the kinds of transf ...

... How does f(x0) relate to averages of f(x) at nearby positions? Therefore fε(0) = f(0) + (ε/d) ∇2 f(0) + … The Laplacian provides a measure of how the spherical average of a function changes as the radius increases. Quantum mechanics is a mystery, but in so far as a classical interaction V(x) at a ...
