Bayesian variational regularization on the ball
CoRR, 2021 We develop variational regularization methods which leverage sparsity-promoting priors to solve severely ill posed inverse problems defined on the 3D ball (i.e. the solid sphere). Our method solves the problem natively on the ball and thus does not suffer from discontinuities that plague alternate approaches where each spherical shell is considered ...

Fluid queues and regular variation [PDF]
Performance Evaluation, 1996 Summary: This paper considers a fluid queueing system, fed by N independent sources that alternate between silence and activity periods. We assume that the distribution of the activity periods of one or more sources is a regularly varying function of index \(\zeta\) .

Top Incomes, Heavy Tails, and Rank-Size Regressions
Econometrics, 2018 In economics, rank-size regressions provide popular estimators of tail exponents of heavy-tailed distributions. We discuss the properties of this approach when the tail of the distribution is regularly varying rather than strictly Pareto.

A Note on Second Order Conditions in Extreme Value Theory: Linking General and Heavy Tail Conditions
Revstat Statistical Journal, 2007 Second order conditions ruling the rate of convergence in any first order condition involving regular variation and assuring a unified extreme value limiting distribution function for the sequence of maximum values, linearly normalized, have appeared in

Asymptotic behavior of positive solutions of a semilinear Dirichlet problem in the annulus [PDF]
Opuscula Mathematica, 2015 In this paper, we establish existence and asymptotic behavior of a positive classical solution to the following semilinear boundary value problem: \[-\Delta u=q(x)u^{\sigma }\;\text{in}\;\Omega,\quad u_{|\partial\Omega}=0.\] Here \(\Omega\) is an annulus

Regularized Mixed Variational‐Like Inequalities [PDF]
Journal 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.
