Numerical Range of Two Operators in Semi-Inner Product Spaces [PDF]
In this paper, the numerical range for two operators both linear and nonlinear have been studied in semi-inner product spaces. The inclusion relations between numerical range, approximate point spectrum, compression spectrum, eigenspectrum, and spectrum ...

A soft–hard tri‐layer composite electrolyte that couples fast Li+ transport with reinforced interfacial stability to enable high‐conductivity, mechanically robust, dendrite‐free lithium‐metal batteries. ABSTRACT The development of solid polymer electrolytes is central to safe, high‐energy lithium‐metal batteries (LMBs); however, persistent challenges ...

On strictly convex and strictly 2-convex 2-normed spaces II
In this paper a new duality mapping is defined, and it is our object to show that there is a similarity among these three types of characterizations of a strictly convex 2-normed space.

Schematic illustration of a sustainable nanofabrication process: chitosan derived from natural sources is used as a biodegradable thin film resist, patterned via Constant Pulse‐Assisted Force Lithography (CP‐AFL) to create tunable nanogrooves. These grooves template gold nanowire formation, enabling high‐resolution nanopatterning under ambient ...

On inequalities satisfied by tuples of operators in semi-Hilbert spaces
In this paper, we study ( α , β ) $(\alpha ,\beta )$ -A-normal tuples of operators acting on semi-Hilbertian spaces, that is, Hilbert-like spaces endowed with a positive bounded operator A inducing a semi-inner product.

Upper Bounds for the Distance to Finite-Dimensional Subspaces in Inner Product Spaces
We establish upper bounds for the distance to finite-dimensional subspaces in inner product spaces and improve some generalisations of Bessel’s inequality obtained by Boas, Bellman and Bombieri.
