Convergence rates for upwind schemes with rough coefficients
This paper is concerned with the numerical analysis of the explicit upwind finite volume scheme for numerically solving continuity equations. We are interested in the case where the advecting velocity field has spatial Sobolev regularity and initial data

Approximation by ψ‐Baskakov‐Kantorovich Operators
ABSTRACT In this paper, we introduce a new family of Baskakov‐Kantorovich operators that depend on a function ψ$$ \psi $$. We compare these new ψ$$ \psi $$‐Baskakov‐Kantorovich operators with the classical Baskakov‐Kantorovich operators to evaluate their approximation results.

A characterization of operator order
As an application of the grand Furuta inequality, we shall show a characterization of usual order associated with operator equation and a Kantorovich type order preserving operator inequality by using essentially the same idea of [9].

Extensions of inequalities involving Kantorovich constant [PDF]
In this paper, two methods of extending inequalities involving Kantorovich constant are presented. An inequality of Micic et al. [Linear Algebra Appl., 318 (2000), 87–107] on positive linear maps and geometric mean of positive definite matrices is extended to arbitrary matrices having accretive transformation. A result of Dragomir [JIPAM 5 (3), Art.76,

Multivariate Neural Network Operators: Simultaneous Approximation and Voronovskaja‐Type Theorem
ABSTRACT In this paper, the simultaneous approximation and a Voronoskaja‐type theorem for the multivariate neural network operators of the Kantorovich type have been proved. In order to establish such results, a suitable multivariate Strang–Fix type condition has been assumed.

This exploratory study establishes the unbalanced Sinkhorn divergence as a robust spatial forecast verification metric for precipitation data. It has illustrative transport vectors which highlight regions where a feature is missing and is shown to align with expert assessments amongst other favourable characteristics with few limitations.

Using decomposition of the nonlinear operator for solving non‐differentiable problems
Starting from the decomposition method for operators, we consider Newton‐like iterative processes for approximating solutions of nonlinear operators in Banach spaces. These iterative processes maintain the quadratic convergence of Newton's method.

Note on Qualitative Robustness of Multivariate Sample Mean and Median
It is known that the robustness properties of estimators depend on the choice of a metric in the space of distributions. We introduce a version of Hampel's qualitative robustness that takes into account the n-asymptotic normality of estimators in Rk, and
