Journal of Functional Analysis, 1996 Let \(X\) be a separable Banach space and let \((U_n)\) be a sequence of linear operators \(U_n: X\to X\). \((U_n)\) factors uniformly \(\ell^{m_n}_p\)'s with respect to \(\lambda\), if there exists a sequence of positive integers \((m_n)\) and sequences of linear operators \((T_n)\), \((S_n)\), with \(T_n:X\to\ell^{m_n}_p\), \(S_n:\ell^{m_n}_p\to X ...

The (D) Property in Banach Spaces [PDF]
Abstract and Applied Analysis, 2012 A Banach space E is said to have (D) property if every bounded linear operator T : F → E* is weakly compact for every Banach space F whose dual does not contain an isomorphic copy of l∞. Studying this property in connection with other geometric properties, we show that every Banach space whose dual has (V∗) property of Pełczyński (and hence every ...

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.ABSTRACT Low water activity ingredients, including dried fruits, vegetables, herbs, and spices, are widely used in ready‐to‐eat (RTE) and non‐RTE foods. Although low water activity limits microbial growth, bacterial pathogens can survive for extended periods in these products.

Some Remarks on Smooth Mappings of Hilbert and Banach Spaces and Their Local Convexity Property
AxiomsWe analyze smooth nonlinear mappings for Hilbert and Banach spaces that carry small balls to convex sets, provided that the radii of the balls are small enough.

Type and cotype of some Banach spaces
International Journal of Mathematics and Mathematical Sciences, 1992 Type and cotype are computed for Banach spaces generated by some positive sublinear operators and Banach function spaces. Applications of the results yield that under certain assumptions Clarkson's inequalities hold in these spaces.

Adaptive Estimation for Weakly Dependent Functional Times Series
Journal of Time Series Analysis, Volume 47, Issue 5, Page 1013-1027, September 2026.ABSTRACT We propose adaptive mean and autocovariance function estimators for stationary functional time series under 𝕃p−m‐approximability assumptions. These estimators are designed to adapt to the regularity of the curves and to accommodate both sparse and dense data designs.

Pruitt’s Estimates in Banach Space [PDF]
Journal of Theoretical Probability, 2009 Pruitt's estimates on the expectation and the distribution of the time taken by a random walk to exit a ball of radius r are extended to the infinite dimensional setting. It is shown that they separate into two pairs of estimates depending on whether the space is type 2 or cotype 2.

t-Best Proximity Pair in Fuzzy Normed Spaces
Journal of Mathematical Extension, 2014 This study has considered the problem of finding best proximity pair in fuzzy metric spaces and uniformly convex fuzzy Banach spaces for fuzzy cyclic contraction map. We prove the uniqueness of this point in uniformly fuzzy Banach spaces. We also give

On the chain of commuting operators on Banach spaces
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract An operator T$T$ on a Banach space is said to be of chain N$N$ if there exist non‐scalar operators S1,⋯,SN−1$S_1,\dots,S_{N-1}$ and a non‐zero compact operator K$K$ such that T↔S1↔S2↔⋯↔SN−1↔K,$$\begin{equation*} T \leftrightarrow S_1 \leftrightarrow S_2 \leftrightarrow \dots \leftrightarrow S_{N-1} \leftrightarrow K, \end{equation*}$$where A↔B$
