Directional total generalized variation regularization [PDF]
In inverse problems, prior information and a priori-based regularization techniques play important roles. In this paper, we focus on image restoration problems, especially on restoring images whose texture mainly follow one direction. In order to incorporate the directional information, we propose a new directional total generalized variation (DTGV ...

Regularly varying probability densities [PDF]
The convolution of regularly varying probability densities is proved asymptotic to their sum, and hence is also regularly varying.

Models with hidden regular variation: Generation and detection
We review the notions of multivariate regular variation (MRV) and hidden regular variation (HRV) for distributions of random vectors and then discuss methods for generating models exhibiting both properties concentrating on the non-negative orthant in ...

Singular solutions for divergence-form elliptic equations involving regular variation theory: Existence and classification [PDF]
We generalise and sharpen several recent results in the literature regarding the existence and complete classification of the isolated singularities for a broad class of nonlinear elliptic equations of the form \begin{equation} -{\rm div}\,(\mathcal A(|x|

In this paper, functional convergence is derived for the partial maxima stochastic processes of multivariate linear processes with weakly dependent heavy-tailed innovations and random coefficients. The convergence takes place in the space of ${\mathbb{R}^

A possible effect of atmospheric circulation in the daily variation of the earth's magnetic field. II. [PDF]
Seasonal features that are not related in a simple way to solar declination occur in the daily variation of the horizontal intensity of the earth's magnetic field at Tucson, as at Honolulu studied previously.

The weak Pareto law and regular variation in the tails
We show that the weak Pareto law, as used to characterize the tail behaviour of income distributions, implies regularly varying tail probabilities, but that the reverse implication does not hold. We also establish implications among other versions of the

Regularly Varying Measures on Metric Spaces: Hidden Regular Variation and Hidden Jumps
We develop a framework for regularly varying measures on complete separable metric spaces $\mathbb{S}$ with a closed cone $\mathbb{C}$ removed, extending material in Hult & Lindskog (2006), Das, Mitra & Resnick (2013).

Existence and boundary behavior of positive solutions for a Sturm-Liouville problem [PDF]
In this paper, we discuss existence, uniqueness and boundary behavior of a positive solution to the following nonlinear Sturm-Liouville problem \[\begin{aligned}&\frac{1}{A}(Au^{\prime })^{\prime }+a(t)u^{\sigma}=0\;\;\text{in}\;(0,1),\\ &\lim\limits_{t ...
