Fundamental solutions of partial derivatives on a half-space

Onirban Islam

The Dirac operator on a globally hyperbolic spacetime admits unique retarded and advanced fundamental solutions. They are well-known to be Lagrangian distributions. Recently, Bär and Gehring...

The mathematics of causal set theory

Sumati Surya (Raman Research Institute, Bangalore, India)

Causal set theory is a discrete  approach to quantum gravity, where the Lorentzian spacetime continuum is replaced by locally finite partially ordered sets. The latter, which we call a "causal set" is...

A Short Introduction to Estimation of Permuted Bi-Isotonic Matrices

Max Graf

Abstract:
As motivation, we consider a bunch of experts responding to a set of questions, where we can observe whether an expert answers a question correctly or not. Assume that for every pair of...

Local time approximation in parameter estimation for skew-sticky diffusions

Sara Mazzonetto (Univ. de Lorraine, Nancy)

In this seminar we first describe a class of real Markov processes with continuous sample paths which
shows singular behavior at a point, let us say barrier. The barrier is semi-permeable or sticky....

Regularity results for locally integrable subharmonic functions on local Dirichlet spaces

Prof. Dr. Peter Stollmann (Chemnitz)

Abstract: We report on recent results from a joint work with B. Güneysu, S. Pigola and. G. Veronelli. Using a new notion of subharmonicity we can prove a version of the Braverman-Milatovic-Shubin...
