Multidimensional extremal dependence coefficients [PDF]

Statistics and Probability Letters, 2018
Extreme values modeling has attracting the attention of researchers in diverse areas such as the environment, engineering, or finance. Multivariate extreme value distributions are particularly suitable to model the tails of multidimensional phenomena. The analysis of the dependence among multivariate maxima is useful to evaluate risk.

Third-order Hankel determinant sharp estimates for the inverse of complex valued holomorphic functions [PDF]

Heliyon
Determining coefficient estimates of inverse complex valued function is often more challenging than determining the function itself, leading to a lack of articles on inverse functions by examining sharp estimates of the third-order Hankel determinant ...

Several Extreme Coefficients of the Tutte Polynomial of Graphs [PDF]

Graphs and Combinatorics, 2020
Let $t_{i,j}$ be the coefficient of $x^iy^j$ in the Tutte polynomial $T(G;x,y)$ of a connected bridgeless and loopless graph $G$ with order $n$ and size $m$. It is trivial that $t_{0,m-n+1}=1$ and $t_{n-1,0}=1$. In this paper, we obtain expressions of another eight extreme coefficients $t_{i,j}$'s with $(i,j)=(0,m-n)$,$(0,m-n-1)$,$(n-2,0)$,$(n-3,0 ...

Optimal recovery of derivatives of Hardy class functions [PDF]

E3S Web of Conferences, 2019
The paper considers the best linear method for approximating the values of derivatives of Hardy class functions in the unit circle at zero according to the information about the values of functions at a finite number of points z1,...,zn that form a ...

Stable tail dependence functions – some basic properties

Dependence Modeling, 2022

Dissecting the Multivariate Extremal Index and Tail Dependence

Revstat Statistical Journal, 2020
A central issue in the theory of extreme values focuses on suitable conditions such that the well[1]known results for the limiting distributions of the maximum of i.i.d. sequences can be applied to stationary ones.
