Cauchy problems for functional evolution inclusions involving accretive operators

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
We study the existence and stability of solutions for a class of nonlinear functional evolution inclusions involving accretive operators. Our approach is employing the fixed point theory for multivalued maps and using estimates via the Hausdorff measure ...

Fundamental Solutions and Green's Functions for Certain Elliptic Differential Operators From a Pseudodifferential Algebra

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 13, Page 12654-12674, September 2025.
ABSTRACT We have studied possible applications of a particular pseudodifferential algebra in singular analysis for the construction of fundamental solutions and Green's functions of a certain class of elliptic partial differential operators. The pseudodifferential algebra considered in the present work, comprises degenerate partial differential ...

Halfspace Depth

open access: yesWIREs Computational Statistics, Volume 17, Issue 3, September 2025.
The halfspace depth generalizes quantiles to multivariate data. This is a bagplot—a depth‐based analog of a boxplot. It succinctly captures the geometry of the bivariate dataset (blue/red points) and identifies the four red points in the top left corner as deviating from the general pattern of the data.

Measure of noncompactness of operators and matrices on the spaces c and c0

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
In this note, using the Hausdorff measure of noncompactness, necessary and sufficient conditions are formulated for a linear operator and matrices between the spaces c and c0 to be compact.

Minimal Riesz Energy Point Configurations for Rectifiable d-Dimensional Manifolds

open access: yes, 2004
For a compact set A in Euclidean space we consider the asymptotic behavior of optimal (and near optimal) N-point configurations that minimize the Riesz s-energy (corresponding to the potential 1/t^s) over all N-point subsets of A, where s>0.

Application of Explainable Artificial Intelligence (XAI) Techniques in Patients With Intracranial Hemorrhage: A Systematic Review

open access: yesWIREs Data Mining and Knowledge Discovery, Volume 15, Issue 3, September 2025.
The graphical abstract highlights the three key aspects addressed in this review: (1) the clinical background of intracranial hemorrhage (IH), providing context for its diagnosis and clinical significance; (2) the technical background of explainable artificial intelligence (XAI) methods relevant to IH‐related tasks; and (3) a systematic review of ...

Cheeger's differentiation theorem via the multilinear Kakeya inequality

open access: yes, 2019
Suppose that $(X,d,\mu)$ is a metric measure space of finite Hausdorff dimension and that, for every Lipschitz $f \colon X \to \mathbb R$, $\operatorname{Lip}(f,\cdot)$ is dominated by every upper gradient of $f$.
