Spectral and functional inequalities on antisymmetric functions

Ufimskii Matematicheskii Zhurnal
We obtain a number of spectral and functional inequalities related to Schrödinger operators defined on antisymmetric functions. Among them are Lieb - Thirring and CLR inequalities. Besides, we find new constants for the Sobolev and the Gagliardo - Nirenberg inequalities restricted to antisymmetric functions.

Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

Asian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Reception Baseline Assessment and ‘small acts’ of micro‐resistance

British Educational Research Journal, EarlyView.
Abstract In September 2021, following the global COVID‐19 pandemic, the Department for Education introduced a national standardised digital Reception Baseline Assessment (RBA) for all English 4‐year‐old children. We analyse RBA and its associated Quality Monitoring Visits, as a further intensification of the new public management of early years ...

Some new numerical radius inequalities via an improved version of the triangle inequality

Journal of Inequalities and Applications
In this paper, we establish several new numerical radius inequalities for bounded linear operators on complex Hilbert spaces by employing refined versions of the classical triangle inequality.

Contrasting roles of school and public libraries in lower primary pupils' reading

British Educational Research Journal, EarlyView.
Abstract Libraries represent an important institutional component of children's reading socialisation, yet their role is often treated as uniform despite substantial differences between school and public libraries. This study examines how visits to school and public libraries relate to pupils' reading attitudes, practices and self‐assessed reading ...

How do secondary schools in England talk about modern languages? A corpus‐assisted discourse analysis of school websites

British Educational Research Journal, EarlyView.
Abstract Situating the study within an ecological perspective on language education, this article examines how secondary schools in England present Modern Languages (MLs) on official school websites. Focusing on 44 schools in Local Authorities with the lowest percentage average entry for the Languages pillar of the EBacc, we built a text database ...

Additive Functional Inequalities in Banach Modules

Journal of Inequalities and Applications, 2008
We investigate the following functional inequality in Banach modules over a -algebra and prove the generalized Hyers-Ulam stability of linear mappings in Banach modules over a -algebra in the spirit of the Th. M. Rassias stability approach. Moreover,

The epistemic ceiling: Veteran practitioners' perspectives on primary qualification entry standards for teaching secondary mathematics in Scotland

British Educational Research Journal, EarlyView.
Abstract This paper presents an exploratory analysis of contemporary curricular and professional qualification policies in the Scottish education system, focusing on minimum qualification thresholds for mathematics teaching. The study examines how veteran secondary mathematics practitioners perceive the structural and pedagogical implications of using ...

Functional Inequalities for Generalized Complete Elliptic Integrals with Two Parameters

Journal of Function Spaces, 2019
In this paper, we establish some functional inequalities for generalized complete elliptic integrals with two parameters, such as estimation of bounds and mean inequalities.
