A group of isometries with non-closed orbits
Herbert Abels, Antonios Manoussos
In this note we give an example of a one-dimensional manifold with two connected components and a complete metric whose group of isometries has an orbit which is not closed. This a…
Suppression of thermally activated escape by heating
Sebastian Getfert, Peter Reimann
The problem of thermally activated escape over a potential barrier is solved by means of path integrals for one-dimensional reaction dynamics with very general time dependences. Fo…
Local-Global Principle for Transvection Groups
A. Bak, Rabeya Basu, Ravi A. Rao
In this article we extend the validity Suslin's Local-Global Principle for the elementary transvection subgroup of the general linear group, the symplectic group, and the orthogona…
Harnack Inequalities and Applications for Ornstein-Uhlenbeck Semigroups with Jump
Shun-Xiang Ouyang, Michael Röckner, Feng-Yu Wang
The Harnack inequality established in [13] for generalized Mehler semigroup is improved and generalized. As applications, the log-Harnack inequality, the strong Feller property, th…
Power spectra from an inflaton coupled to the Gauss-Bonnet term
Zong-Kuan Guo, Dominik J. Schwarz
We consider power-law inflation with a Gauss-Bonnet correction inspired by string theory. We analyze the stability of cosmological perturbations and obtain the allowed parameter sp…
Characteristic Polynomials of Sample Covariance Matrices
Holger Kösters
We investigate the second-order correlation function of the characteristic polynomial of a sample covariance matrix. Starting from an explicit formula for the generating function,…
