A Heat Kernel Approach to Interest Rate Models

Jiro Akahori, Yuji Hishida, Josef Teichmann +1

We construct default-free interest rate models in the spirit of the well-known Markov funcional models: our focus is analytic tractability of the models and generality of the appro…

High Resolution Long- and Short-Term Earthquake Forecasts for California

M. J. Werner, A. Helmstetter, D. D. Jackson +1

We present two models for estimating the probabilities of future earthquakes in California, to be tested in the Collaboratory for the Study of Earthquake Predictability (CSEP). The…

A formalism for analyzing vacuum spacetimes

Michael Reiterer, Eugene Trubowitz

The Einstein vacuum equations in the formulation developed by Newman, Penrose [NP] and Friedrich [Fr] are expressed in terms of a Lie superbracket. Differential identities are deri…

Bandwidth, expansion, treewidth, separators, and universality for bounded degree graphs

Julia Böttcher, Klaas P. Pruessmann, Anusch Taraz +1

We establish relations between the bandwidth and the treewidth of bounded degree graphs G, and relate these parameters to the size of a separator of G as well as the size of an exp…

Expectation Maximization as Message Passing - Part I: Principles and Gaussian Messages

Justin Dauwels, Andrew Eckford, Sascha Korl +1

It is shown how expectation maximization (EM) may be viewed as a message passing algorithm in factor graphs. In particular, a general EM message computation rule is identified. As…

Study of diffuse scattering under hydrostatic pressure in PbMg1/3Nb2/3O3

G -M Rotaru, B Padmanabhan, S N Gvasaliya +5

We report measurements of the evolution of the diffuse scattering in a single crystal PbMg1/3Nb2/3O3 as a function of hydrostatic pressure. Upon applying pressure the diffuse scatt…
