What is the blog?

This blog is a re-interpretation of the tessendorf.org website I had for several years. At the moment I am putting up the papers and reports page. Eventually I will put up the other pages on frumple and old Arete Image Software materials. You can also find this information at my university page

Numerical Integration of the Feynman Path Integral for Radiative Transport

The radiative transport problem is cast in integral form using a transport kernel. The transport kernel has an explicit representation in terms of a Feynman Path Integral over all paths between selected points in a volume. This representation is setup in detail. Numerical evaluation of this Path Integral is formulated with a Frenet-Serret based procedure for generating valid random paths, and with a numerical evaluation of the weight for each valid path. Very early sanity checks of a numerical implementation are reported. Approaches to optimization are identified.
