Locally definite normal operators in Krein spaces
Friedrich Philipp
We introduce the spectral points of two-sided positive type of bounded normal operators in Krein spaces. It is shown that a normal operator has a local spectral function on sets wh…
A note on essential smoothness in the Heston model
Martin Forde, Antoine Jacquier, Aleksandar Mijatovic
This note studies an issue relating to essential smoothness that can arise when the theory of large deviations is applied to a certain option pricing formula in the Heston model. T…
The Impact of non-DLVO Forces on the Onset of Shear Thickening of Concentrated Electrically Stabilized Suspensions
Joachim Kaldasch, Bernhard Senge, Jozua Laven
This paper exposes an extension of an activation model previously published by the authors. When particles arranged along the compression axis of a sheared suspension, they may ove…
Shear thickening in Electrically Stabilized Colloidal Suspensions
Joachim Kaldasch, Bernhard Senge, Jozua Laven
A theory is presented for the onset of shear thickening in colloidal suspensions of particles, stabilized by an electrostatic repulsion. Based on an activation model a critical she…
ShearLab: A Rational Design of a Digital Parabolic Scaling Algorithm
Gitta Kutyniok, Morteza Shahram, Xiaosheng Zhuang
Multivariate problems are typically governed by anisotropic features such as edges in images. A common bracket of most of the various directional representation systems which have…
Illumination problems on translation surfaces with planar infinities
Nikolay Dimitrov
In the current article we discuss an illumination problem proposed by Urrutia and Zaks. The focus is on configurations of finitely many two-sided mirrors in the plane together with…
