About the geometrical stability of the marginal terms in variation series

open access: yesLietuvos Matematikos Rinkinys, 2004
It was proved that the logistic minimum is geometrically min-stable, positional statistics  X(kN) ,  k > 1 are not geometrically stable, common minimum and maximum distributions are not asimptotically indepen­dent as the sample size is geometrical.

Bi-free extreme values

open access: yesJournal of Functional Analysis, 2020
In this paper, we continue Voiculescu's recent work on the analogous extreme value theory in the context of bi-free probability theory. We derive various equivalent conditions for a bivariate distribution function to be bi-freely max-infinitely divisible.

Extreme-Value Copulas [PDF]

open access: yes, 2009
Being the limits of copulas of componentwise maxima in independent random samples, extreme-value copulas can be considered to provide appropriate models for the dependence structure between rare events.

Prudent decisions to estimate the risk of loss in insurance

open access: yesTechnological and Economic Development of Economy, 2017
The directive 2009/138/EC „Solvency II”, provides the determination of insurance capital requirements based either on a standard formula or an internal model built by the company and approved by the regulatory authority.

Extreme value distributions and Renormalization Group [PDF]

open access: yes, 2012
In the classical theorems of extreme value theory the limits of suitably rescaled maxima of sequences of independent, identically distributed random variables are studied. So far, only affine rescalings have been considered.

Perturbed and Unperturbed: Analyzing the Conservatively Perturbed Equilibrium (Linear Case)

open access: yesEntropy, 2020
The “conservatively perturbed equilibrium” (CPE) technique for a complex chemical system is computationally analyzed in a batch reactor considering different linear mechanisms with three and four species.

Application of Non-stationary Extreme Value Analysis to Satellite-Observed Sea Surface Temperature Data for Past Decades

open access: yesFrontiers in Marine Science, 2022
Extreme value analysis (EVA) has been extensively used to understand and predict long-term return extreme values. This study provides the first approach to EVA using satellite-observed sea surface temperature (SST) data over the past decades ...

Almost Sure Convergence for the Maximum and Minimum of Normal Vector Sequences

open access: yesMathematics, 2020
In this paper, we prove the almost sure convergences for the maximum and minimum of nonstationary and stationary standardized normal vector sequences under some suitable conditions.
