Ultraregular inductive limits

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
An inductive limit E=indlim En is ultraregular if it is regular and each set B⊂En, which is bounded in E, is also bounded in En. A necessary and sufficient condition for ultraregularity of E is given provided each En is an LF-space which is closed in En ...

Sharp rate of average decay of the Fourier transform of a bounded set [PDF]

open access: yes, 2003
We prove that the spherical mean of the Fourier transform of the characteristic function of a bounded convex set (without any additional assumptions) or a bounded set with a C^{3/2} boundary decays at infinity at the same rate as the Fourier transform of

Traces and Extensions of Bounded Divergence-Measure Fields on Rough Open Sets

open access: yes, 2020
We prove that an open set $\Omega \subset \mathbb{R}^n$ can be approximated by smooth sets of uniformly bounded perimeter from the interior if and only if the open set $\Omega$ satisfies \begin{align*} &\qquad \qquad\qquad\qquad\qquad\qquad\qquad ...

On the set of L-space surgeries for links [PDF]

open access: yes, 2017
It it known that the set of L-space surgeries on a nontrivial L-space knot is always bounded from below. However, already for two-component torus links the set of L-space surgeries might be unbounded from below.

(Quasi)-uniformities on the set of bounded maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
From real analysis it is known that if a sequence {fn,   n∈ℕ} of real-valued functions defined and bounded on X⊂ℝ converges uniformly to f, then f is also bounded and the sequence {fn,   n∈ℕ}. In the present paper we generalize results as the above using

Prime preideals on bounded EQ-algebras

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
EQ-algebras were introduced by Novák in [14] as an algebraic structure of truth values for fuzzy type theory (FFT). In [1], Borzooei et. al. introduced the notion of preideal in bounded EQ-algebras.

Application of quasi-f -power increasing sequence in absolute ph - |C, a, b; d; l| of infinite series [PDF]

open access: yesMathematica Moravica, 2021
An increasing quasi-f-power sequence of a wider class has been used to establish a universal theorem on a least set of conditions, which is sufficient for an infinite series to be generalized ph-|C, a, b; d; l| k summable.

Bounded and relatively bounded sets [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1987
All subsets of a field that are intersections of almost-orders of the field are characterised, and all ring topologies on a field which are not finer than any nontrivial locally bounded ring are characterised.

Reductions to the set of random strings: The resource-bounded case [PDF]

open access: yesLogical Methods in Computer Science, 2014
This paper is motivated by a conjecture that BPP can be characterized in terms of polynomial-time nonadaptive reductions to the set of Kolmogorov-random strings.

$\ell^1$-Bounded Sets

open access: yes, 2023
A subset $M$ of a separable Hilbert space $H$ is $\ell^1$-bounded if there exists a Riesz basis $\mathcal{F} = \{e_n\}_{n \in \mathbb{N}}$ for $H$ such that $\sup_{x \in M} \sum_{n \in \mathbb{N}} |\langle x, e_n\rangle| < \infty.$ A similar definition for $\ell^1$-frame-bounded sets is made by replacing Riesz bases with frames.
