Totally geodesic submanifolds of the complex and the quaternionic 2-Grassmannians
Sebastian Klein
In this article, I classify the totally geodesic submanifolds in the complex 2-Grassmannians and in the quaternionic 2-Grassmannians. It turns out that for both of these spaces, th…
On the path structure of a semimartingale arising from monotone probability theory
Alexander C. R. Belton
Let be the unique normal martingale such that and \[\mathrm{d}[X]_t=(1-t-X_{t-}) \mathrm{d}X_t+\mathrm{d}t\] and let for all ; the semimartingale…
Small weakly universal Turing machines
Turlough Neary, Damien Woods
We give small universal Turing machines with state-symbol pairs of (6, 2), (3, 3) and (2, 4). These machines are weakly universal, which means that they have an infinitely repeated…
Determinantal transition kernels for some interacting particles on the line
A. B. Dieker, J. Warren
We find the transition kernels for four Markovian interacting particle systems on the line, by proving that each of these kernels is intertwined with a Karlin-McGregor type kernel.…
Filtering and estimation in stochastic volatility models with rationally distributed disturbances
Bernard Hanzon, Wolfgang Scherrer
This paper deals with the filtering problem for a class of discrete time stochastic volatility models in which the disturbances have rational probability density functions. This in…
The light curve of the companion to PSR B1957+20
Mark Reynolds, Paul Callanan, Andrew Fruchter +3
We present a new analysis of the light curve for the secondary star in the eclipsing binary millisecond pulsar system PSR B1957+20. Combining previous data and new data points at m…
