Extremes and Regular Variation [PDF]

open access: yes, 2021
We survey the connections between extreme-value theory and regular variation, in one and higher dimensions, from the algebraic point of view of our recent work on Popa groups.

REGULAR VARIATION AND SMILE ASYMPTOTICS [PDF]

open access: yesMathematical Finance, 2009
We consider risk‐neutral returns and show how their tail asymptotics translate directly to asymptotics of the implied volatility smile, thereby sharpening Roger Lee's celebrated moment formula. The theory of regular variation provides the ideal mathematical framework to formulate and prove such results.

Polynomial tails of additive-type recursions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Polynomial bounds and tail estimates are derived for additive random recursive sequences, which typically arise as functionals of recursive structures, of random trees, or in recursive algorithms.

Regularized Mixed Variational‐Like Inequalities [PDF]

open access: yesJournal of Applied Mathematics, 2012
We use auxiliary principle technique coupled with iterative regularization method to suggest and analyze some new iterative methods for solving mixed variational‐like inequalities. The convergence analysis of these new iterative schemes is considered under some suitable conditions. Some special cases are also discussed.

Sparse regular variation

open access: yesAdvances in Applied Probability, 2021
AbstractRegular variation provides a convenient theoretical framework for studying large events. In the multivariate setting, the spectral measure characterizes the dependence structure of the extremes. This measure gathers information on the localization of extreme events and often has sparse support since severe events do not simultaneously occur in ...

Even Order Half-Linear Differential Equations with Regularly Varying Coefficients

open access: yesMathematics, 2020
We establish nonoscillation criterion for the even order half-linear differential equation (−1)nfn(t)Φx(n)(n)+∑l=1n(−1)n−lβn−lfn−l(t)Φx(n−l)(n−l)=0, where β0,β1,…,βn−1 are real numbers, n∈N, Φ(s)=sp−1sgns for s∈R, p∈(1,∞) and fn−l is a regularly varying (

On regular variation of entire Dirichlet series

open access: yesМатематичні Студії, 2023
Consider an entire (absolutely convergent in $\mathbb{C}$) Dirichlet series $F$ with the exponents $\lambda_n$, i.e., of the form $F(s)=\sum_{n=0}^\infty a_ne^{s\lambda_n}$, and, for all $\sigma\in\mathbb{R}$, put $\mu(\sigma,F)=\max\{|a_n|e^{\sigma ...

Half-linear differential equations: Regular variation, principal solutions, and asymptotic classes

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
We are interested in the structure of the solution space of second-order half-linear differential equations taking into account various classifications regarding asymptotics of solutions.

Topological regular variation: III. Regular variation

open access: yesTopology and its Applications, 2010
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.
