Cauchy's functional equation and extensions: Goldie's equation and inequality, the Go{\l}\k{a}b-Schinzel equation and Beurling's equation [PDF]
The Cauchy functional equation is not only the most important single functional equation, it is also central to regular variation. Classical Karamata regular variation involves a functional equation and inequality due to Goldie; we study this, and its ...

Topological regular variation: III. Regular variation
The paper extends the topological theory of regular variation of the slowly varying case of \textit{N. H. Bingham} and \textit{A. J. Ostaszewski} [Topology Appl. 157, No. 13, 1999--2013 (2010; Zbl 1202.26004)] to the regularly varying functions between metric groups, viewed as normed groups, cf. \textit{N. H. Bingham} and \textit{A. J.

Regularized Zero-Variance Control Variates
Zero-variance control variates (ZV-CV) are a post-processing method to reduce the variance of Monte Carlo estimators of expectations using the derivatives of the log target. Once the derivatives are available, the only additional computational effort lies in solving a linear regression problem.

General inverse problems for regular variation [PDF]
Regular variation of distributional tails is known to be preserved by various linear transformations of some random structures. An inverse problem for regular variation aims at understanding whether the regular variation of a transformed random object is

Second order corrections for the limits of normalized ruin times in the presence of heavy tails
In this paper we consider a compound Poisson risk model with regularly varying claim sizes. For this model in [4] an asymptotic formula for the finite time ruin probability is provided when the time is scaled by the mean excess function. In this paper

Large noise in variational regularization [PDF]
Abstract In this paper we consider variational regularization methods for inverse problems with large noise that is in general unbounded in the image space of the forward operator. We introduce a Banach space setting that allows to define a reasonable notion of solutions for more general noise in a larger space provided that one has ...

Limit laws for random vectors with an extreme component [PDF]
Models based on assumptions of multivariate regular variation and hidden regular variation provide ways to describe a broad range of extremal dependence structures when marginal distributions are heavy tailed.
