On the Reducibility of Weighted Composition Operators Generated by Periodic Transformations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In this article, we study the reducibility of weighted composition operators (also known as weighted displacement operators) acting on Banach spaces of continuous functions on a compact topological space X. We consider operators of the form Bu(x) = a(x)u(α(x)), where α : X⟶X is a continuous mapping and a is a continuous function.

Approximation properties by Schurer type q-Kantorovich–Stancu shifted knots operators

open access: yesJournal of Inequalities and Applications
We design the Schurer type Kantorovich–Stancu operators by using shifted knots in the quantum calculus. We obtain the convergence and other related approximation properties of these operators.

On the Approximation Process of Shifted‐Knots Bivariate Stancu‐Type Kantorovich Operators

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This paper focuses on defining bivariate Stancu‐type Kantorovich operators with the technique associated with the idea of shifted knots. The degree of approximation and weighted approximation of these bivariate operators are estimated, respectively, by means of Lipschitz kind bivariate functions and weighted functions of two variables. Furthermore, the

Rate of approximation of blending type modified univariate and bivariate λ-Schurer-Kantorovich operators

open access: yesKuwait Journal of Science
In this work, we investigate some approximation properties of blending type univariate and bivariate Schurer-Kantorovich operators based on shape parameter λ ∈ [−1, 1]. We evaluate some moment estimates and obtain several direct theorems.

Household Portfolios and Monetary Policy

open access: yesInternational Journal of Finance &Economics, Volume 30, Issue 4, Page 4358-4377, October 2025.
ABSTRACT We show that expansionary monetary policy is positively (negatively) associated with household portfolio allocation to high‐risk (low‐risk) assets, in line with ‘reaching for yield’ behaviour. Our main findings are based on an analysis of US household‐level data using alternative measures of monetary policy shifts over the period 1999–2007 ...

STADTMITTE UMSTEIGEN? HEINZ KNOBLOCH AND THE ‘ARCHAEOLOGICAL’ TRACES OF BERLIN'S GHOST STATIONS

open access: yesGerman Life and Letters, Volume 78, Issue 4, Page 527-543, October 2025.
ABSTRACT In 1982, the East German journalist Heinz Knobloch published a volume entitled Stadtmitte umsteigen. Its title was provocative: since the construction of the Berlin Wall, it had not been possible to change trains at Stadtmitte in East Berlin, as one of the two lines functioned only as a transit route between the north and south of West Berlin.

Pointwise approximation by a Stancu variant of Durrmeyer-Schurer operators

open access: yesJournal of Inequalities and Applications
In the present paper, we introduce a kind of Stancu variant of Durrmeyer-Schurer operators which includes non-negative real parameters α and β, and obtain the direct and converse results of approximation by the operators.

A New Modification of Baskakov–Schurer–Stancu Operators: Weighted and Pointwise Approximation Theories

open access: yesMathematics
The behavior of a new modification of operators of the Baskakov–Schurer–Stancu variant is discussed in this study. First, we establish certain necessary moment and central moment estimates.

Willingness to Take Financial Risks and Portfolio Choice: The Moderating Role of Financial Planners' Advice

open access: yesFINANCIAL PLANNING REVIEW, Volume 8, Issue 3, September 2025.
ABSTRACT This study utilizes data from seven waves of the Survey of Consumer Finances to investigate how financial planning advice moderates the relationship between self‐reported financial risk tolerance and two aspects of investment behavior: stock market participation and the proportion of financial wealth allocated to stocks.
