Orbital motion of test particles in regular Hayward black hole space-time

In this paper, all possible orbits of test particles are investigated by using phase plane method in regular Hayward black hole space-time. Expand abstract.

Hadamard renormalization for a charged scalar field

These results will have applications in the computation of renormalized expectation values for a charged quantum scalar field on a charged black hole space-time, and hence in addressing issues such as the quantum stability of the inner horizon. Expand abstract.

The Scattering Map on Oppenheimer--Snyder Spacetime

In this paper we analyse the boundedness of solutions $\phi$ of the wave equation in the Oppenheimer--Snyder model of gravitational collapse in both the case of a reflective dust cloud and a permeating dust cloud. Expand abstract.

Joint H\"older continuity of local time for a class of interacting branching measure valued diffusions

Using a Tanaka representation of the local time for a class of superprocesses with dependent spatial motion, as well as sharp estimates from the theory of uniformly parabolic partial differential equations, the joint H\"older continuity in time and space of said local times is obtained in two and...

Dark matter scattering cross section in Yang-Mills theory

We calculate for the first time the scattering cross section between lightest glueballs in SU(2) pure Yang-Mills theory, which are good candidates of dark matter. Expand abstract.

Parameter estimation for SPDEs based on discrete observations in time and space

Resulting method of moments estimators for the diffusivity and the volatility parameter inherit the asymptotic normality and can be constructed robustly with respect to the sampling frequencies in time and space. Expand abstract.

Higher-spin kinematics & no ghosts on quantum space-time in Yang-Mills matrix models

A classification of bosonic on- and off-shell modes on a cosmological quantum space-time solution of the IIB matrix model is given, which leads to a higher-spin gauge theory. Expand abstract.

Kinetic limit for a chain of harmonic oscillators with a point Langevin thermostat

We consider an infinite chain of coupled harmonic oscillators with a Langevin thermostat attached at the origin and energy, momentum and volume conserving noise that models the collisions between atoms. Expand abstract.
