On the Double Sequence Space Hϑ as an Extension of Hahn Space h
International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.Double sequence spaces have become a significant area of research within functional analysis due to their applications in various branches of mathematics and mathematical physics. In this study, we investigate Hahn double sequence space denoted as Hϑ, where ϑ ∈ {p, bp, r}, as an extension of the Hahn sequence space h.

Shock and Vibration, Volume 2025, Issue 1, 2025.The resin sealing parts obtained by 3D printing have been widely used in underwater sealing due to the ease of adjustment of size. To ensure the successful separation of seals, the blasting line separation technology is used. Numerical simulation and validation experiments are needed to investigate the damage law of resin sealing parts separated ...

On uniform spaces with invariant nonstandard hulls
Journal of Logic and Analysis, 2014 This paper is about nonstandard topology, in the tradition of Luxemburg [\textit{W.~A.~J.~Luxemburg}, A general theory of monads, in: Appl. Model Theory Algebra, Anal., Probab., Proc. Int. Sympos. Calif. Inst. Technol. 1967, 18--86 (1969; Zbl 0207.52402)].

Randomized collective choices based on a fractional tournament
Theoretical Economics, Volume 20, Issue 1, Page 57-92, January 2025.An extension rule assigns to each fractional tournament x (specifying, for every pair of social alternatives a and b, the proportion xab of voters who prefer a to b) a random choice function y (specifying a collective choice probability distribution for each subset of alternatives), which chooses a from {a,b} with probability xab.

Analytic Nullstellensätze and the model theory of valued fields
Mathematische Nachrichten, Volume 297, Issue 8, Page 2873-2917, August 2024.Abstract We present a uniform framework for establishing Nullstellensätze for power series rings using quantifier elimination results for valued fields. As an application, we obtain Nullstellensätze for p$p$‐adic power series (both formal and convergent) analogous to Rückert's complex and Risler's real Nullstellensatz, as well as a p$p$‐adic analytic ...

A unifying Radon-Nikodým theorem through nonstandard hulls
Illinois Journal of Mathematics, 2005 We present a Radon-Nikodým theorem for vector measures of bounded variation that are absolutely continuous with respect to the Lebesgue measure on the unit interval. Traditional Radon-Nikodým derivatives are Banach space-valued Bochner integrable functions defined on the unit interval or some other measure space.

Loan‐to‐value limits as a macroprudential policy tool: Developments in theory and practice
Journal of Economic Surveys, Volume 38, Issue 1, Page 232-267, February 2024.Abstract I analyze the development of the loan‐to‐value (LTV) ratio limit for households as a macroprudential policy tool in both theory and practice, by surveying theoretical and empirical literature. I argue that the practical implementation of LTV caps preceded theoretical studies, but research has caught up since the global financial crisis ...

A robust permutation test for subvector inference in linear regressions
Quantitative Economics, Volume 15, Issue 1, Page 27-87, January 2024.We develop a new permutation test for inference on a subvector of coefficients in linear models. The test is exact when the regressors and the error terms are independent. Then we show that the test is asymptotically of correct level, consistent, and has power against local alternatives when the independence condition is relaxed, under two main ...

Gorenstein simplices and the associated finite abelian groups
, 1910 It is known that a lattice simplex of dimension $d$ corresponds a finite abelian subgroup of $(\mathbb{R}/\mathbb{Z})^{d+1}$. Conversely, given a finite abelian subgroup of $(\mathbb{R}/\mathbb{Z})^{d+1}$ such that the sum of all entries of each element ...
