Using the path-integral formalism, Ryan Parker, Mark Stedman and Luca Capriotti develop an accurate and easy-to-compute semi-analytical approximation for a general class of default intensity models.

This four-day mathematical physics conference takes place in Helsinki, September 3-6, 2024. It covers probabilistic and path integral methods in quantum and statistical field theory, highlighting in ...

In this paper we establish various results involving parallel line-valued conditional Yeh-Wiener integrals of the type E(F(x)∣ x(sj, ·) = ηj(·), j = 1, ..., n) where $0 < s_1 < \cdots < s_n$. We then ...

This paper introduces geometric realizations of homotopic paths over simply-connected surfaces with non-zero curvature as a means of comparing and measuring paths between antipodes with either a ...

The most powerful formula in physics starts with a slender S, the symbol for a sort of sum known as an integral. Further along comes a second S, representing a quantity known as action. Together, ...

A comparison is made of the Millington and BBC methods for calculating attenuation of radio waves over mixed paths and the application of the Millington method is shown for a worked example. The BBC ...
