Domain of the Double Sequential Band Matrix in the Sequence Space
Abstract and Applied Analysis, 2013 The sequence space was introduced by Maddox (1967). Quite recently, the domain of the generalized difference matrix in the sequence space has been investigated by Kirişçi and Başar (2010).

POSITIVE DEFINITE FUNCTIONS AND SHARP INEQUALITIES FOR PERIODIC FUNCTIONS
Ural Mathematical Journal, 2017 Let \(\varphi\) be a positive definite and continuous function on \(\mathbb{R}\), and let \(\mu\) be the corresponding Bochner measure. For fixed \(\varepsilon,\tau\in\mathbb{R}\), \(\varepsilon\ne 0\), we consider a linear operator \(A_{\varepsilon,\tau}

Ecology and Evolution, Volume 16, Issue 6, June 2026.Plumage coloration is widely recognized as an important component in intraspecific communication. Our aim was to examine the variation of oxidative parameters and their associations with the coloration of two different nestling plumage traits in collared flycatchers (Ficedula albicollis).

Financial Statement Information and Equity Value: The Role of Real Options Characteristics
Financial Management, Volume 55, Issue 2, Page 301-328, Summer 2026.ABSTRACT This paper examines whether firm‐specific real options characteristics are equity value‐relevant beyond valuation estimates anchored in financial statements. Using extensive historical data for the United Kingdom, we assess and compare the forecast accuracy and explanatory power for stock prices of equity valuation models based on residual ...

Localization for Riesz means of Fourier expansions [PDF]
, 2013 The classical Riemann localization principle states that if an integrable function of one variable vanishes in an open set, then its Fourier expansion converges to zero in this set.

Distributional asymptotic expansions of spectral functions and of the associated Green kernels
Electronic Journal of Differential Equations, 1999 Asymptotic expansions of Green functions and spectral densities associated with partial differential operators are widely applied in quantum field theory and elsewhere.

Hub‐and‐Spoke Collusion With a Third‐Party Pricing Algorithm
The Journal of Industrial Economics, Volume 74, Issue 2, Page 181-196, June 2026.ABSTRACT A data analytics company delivers an efficiency by supplying a pricing algorithm that allows prices to more effectively respond to demand variation. In this setting, I consider a new form of hub‐and‐spoke collusion: A data analytics company (hub) coordinates the prices of competitors (spokes) through its pricing algorithm.

Some remarks on Bochner-Riesz means [PDF]
, 2000 We study Lp norm convergence of Bochner-Riesz means SδRƒ associated with certain non-negative differential operators. When the kernel SmR (x, y) satisfies a weak estimate for large values of m we prove Lp norm convergence of Sδ Rƒ for
