General discrepancy estimates II: the Haar function system [PDF]

Acta Arithmetica, 1994
H. Niederreiter has developed a powerful technique to estimate the (extreme) discrepancy \[ D_ N ({\mathcal P}) : \sup_{J \in {\mathcal J}} \left | {A(J,N) \over N} - \lambda_ s (J) \right | \] of finite rational point sets \({\mathcal P} = (x_ n)^{N-1}_{n=0}\) in the \(s\)- dimensional unit cube \([0,1[^ s\). Here \({\mathcal J}\) denotes the class of

Variants of a theorem of Macbeath in finite‐dimensional normed spaces

Mathematika, Volume 72, Issue 2, April 2026.
Abstract A classical theorem of Macbeath states that for any integers d⩾2$d \geqslant 2$, n⩾d+1$n \geqslant d+1$, d$d$‐dimensional Euclidean balls are hardest to approximate, in terms of volume difference, by inscribed convex polytopes with n$n$ vertices.

‘It's Like a Different Lens’: How Māori Independent Research Centres Contribute to Aotearoa's Research Sector

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 1, March 2026.
With the announcement and initial proposal for transformation of the Science System in Aotearoa, there is a generational opportunity to recognise and invest in Māori research centres as hubs of Māori research excellence. However, there is no explicit recognition of Māori research centres within this vision, despite literature consistently highlighting ...

Haar wavelet collocation method for existence and numerical solutions of fourth-order integro-differential equations with bounded coefficients

Nonlinear Engineering
In this article, Haar wavelet collocation method is applied for the solution of fourth-order integro-differential equations. Also, a fixed point approach is used to investigate the existence theory of solution to the considered problem.

No Appeasement Through Vibrations: Male Vibratory Pre‐Copulatory Courtship in the Cursorial Spider Pisaura mirabilis Does Not Affect Female Predatory Response

Ethology, Volume 132, Issue 3, Page 183-193, March 2026.
Male courtship can serve various purposes such as species recognition, mate localization, or advertisement of individual quality and physical condition. In predatory species such as spiders, courtship activity by the male might also reduce the risk of being predated on by the female.

Along the Silenced Footsteps of Latin American Pastoralists: From Mexico to Argentina, a Journey Through Pastoral Systems in Latin America

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 1, March 2026.
ABSTRACT Pastoralism worldwide faces a complex landscape of increased pressures and exclusion. Beyond ecological and economic challenges, pastoralists suffer eroding cultural identity, limited generational renewal, and political marginalization. Yet pastoral livelihoods are increasingly recognized as stewards of sustainable futures and amongst the best

Solvability of invariant systems of differential equations on H2$\mathbb {H}^2$ and beyond

Mathematische Nachrichten, Volume 299, Issue 2, Page 456-479, February 2026.
Abstract We show how the Fourier transform for distributional sections of vector bundles over symmetric spaces of non‐compact type G/K$G/K$ can be used for questions of solvability of systems of invariant differential equations in analogy to Hörmander's proof of the Ehrenpreis–Malgrange theorem.

Analyzing the Free States of one Quantum Resource Theory as Resource States of Another

Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.
The article investigates how free states in one quantum resource theory can become highly resourceful in another. It systematically studies multipartite entanglement, fermionic non‐Gaussianity, imaginarity, realness, spin coherence, Clifford non‐stabilizerness, Sn‐equivariance, and non‐uniform entanglement, combining rigorous analytical tools and ...

A higher-order collocation technique based on Haar wavelets for fourth-order nonlinear differential equations having nonlocal integral boundary conditions

Alexandria Engineering Journal
This article encounters the use of two wavelet methods, namely the collocation method based on Haar wavelets (CMHW) and the higher-order collocation method based on Haar wavelets (HCMHW), to solve linear and nonlinear fourth-order differential equations ...

Frame potential of Brownian SYK model of Majorana and Dirac fermions

Journal of High Energy Physics
We consider the Brownian SYK, i.e. a system of N Majorana (Dirac) fermions with a white-noise q-body interaction term. We focus on the dynamics of the Frame potentials, a measure of the scrambling and chaos, given by the moments of the overlap between ...
