The Depositional Record, Volume 11, Issue 4, Page 1029-1062, September 2025.The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...

A robust Corrádi–Hajnal theorem
Random Structures &Algorithms, Volume 65, Issue 1, Page 61-130, August 2024.Abstract For a graph G$$ G $$ and p∈[0,1]$$ p\in \left[0,1\right] $$, we denote by Gp$$ {G}_p $$ the random sparsification of G$$ G $$ obtained by keeping each edge of G$$ G $$ independently, with probability p$$ p $$. We show that there exists a C>0$$ C>0 $$ such that if p≥C(logn)1/3n−2/3$$ p\ge C{\left(\log n\right)}^{1/3}{n}^{-2/3} $$ and G$$ G ...

Existence and Global Asymptotic Behavior of Singular Positive Solutions for Radial Laplacian
Journal of Function Spaces, Volume 2019, Issue 1, 2019., 2019 The aim of this paper is to establish existence and uniqueness of a positive continuous solution to the following singular nonlinear problem. {-t1-ntn-1u′′=a(t)uσ, t∈(0,1010), limt→0tn-1u′(t)=, u()=}, where n ≥ 3, σ < 1, and a denotes a nonnegative continuous function that might have the property of being singular at t = 0 and /or t = 1 and which ...

Scandinavian Journal of Statistics, Volume 51, Issue 2, Page 832-860, June 2024.Abstract In this paper we study two important representations for extreme value distributions and their max‐domains of attraction (MDA), namely von Mises representation (vMR) and variation representation (VR), which are convenient ways to gain limit results. Both VR and vMR are defined via so‐called auxiliary functions ψ. Up to now, however, the set of

A precise asymptotic description of half‐linear differential equations
Mathematische Nachrichten, Volume 297, Issue 4, Page 1275-1309, April 2024.Abstract We study asymptotic behavior of solutions of nonoscillatory second‐order half‐linear differential equations. We give (in some sense optimal) conditions that guarantee generalized regular variation of all solutions, where no sign condition on the potential is assumed.

Methods in half-linear asymptotic theory
Electronic Journal of Differential Equations, 2016 We study the asymptotic behavior of eventually positive solutions of the second-order half-linear differential equation $$ (r(t)|y'|^{\alpha-1}\hbox{sgn} y')'=p(t)|y|^{\alpha-1}\hbox{sgn} y, $$ where r(t) and p(t) are positive continuous functions ...

Second-order boundary estimate for the solution to infinity Laplace equations
Electronic Journal of Differential Equations, 2017 In this article, we establish a second-order estimate for the solutions to the infinity Laplace equation $$ -\Delta_{\infty} u=b(x)g(u), \quad u>0, \quad x \in \Omega,\; u|_{\partial \Omega}=0, $$ where $\Omega$ is a bounded domain in $\mathbb{R ...
