Weak compactness in locally convex spaces [PDF]

open access: yesTransactions of the American Mathematical Society, 1973
The notion of weak compactness plays a central role in the theory of locally convex topological vector spaces. However, in the statement of many theorems, completeness of the space, or at least quasi-completeness of the space in the Mackey topology is an important assumption.

State of the Art of Low‐Frequency Acoustic Modulation: Intensity Enhancement and Directional Control

open access: yesAdvanced Science, EarlyView.
High intensity low‐frequency sound sources hold significant value in many fields. However, their long wavelength, strong penetrability, and tendency to diffract make direction control and intensity enhancement challenging. Acoustic generators and metamaterial‐based acoustic devices still face issues such as low energy efficiency, poor directional ...

On the Dynamics of Abstract Retarded Evolution Equations

open access: yesAbstract and Applied Analysis, 2013
This paper is concerned with the dynamics of the following abstract retarded evolution equation: in a Hilbert space , where is a self-adjoint positive-definite operator with compact resolvent and is a locally Lipschitz continuous mapping.

Metrizability of Locally Compact Vector Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1971
By use of the theory of characters and the Pontryagin-van Kampen theorem, it is shown that if E E is a locally compact vector space over a discrete division ring K K of characteristic zero and if dim K E > 2

Stacked Nanosheet Gate‐All‐Around Morphotropic Phase Boundary Field‐Effect Transistors

open access: yesAdvanced Science, EarlyView.
This study proposes a material design using ferroelectric‐antiferroelectric mixed‐phase HZO to achieve steep subthreshold swing and non‐hysteretic on‐current enhancement in morphotropic phase boundary field‐effect transistors (MPB‐FETs). For the first time, two‐stacked nanosheet GAA MPB‐FETs with optimized HZO are demonstrated, validating superior ...

Wavelet frames in Sobolev space over locally compact abelian group

open access: yesBoletim da Sociedade Paranaense de Matemática
In this paper we construct wavelet frames for continuous and discrete wavelets on Sobolev space over abelian group. A necessary condition and sufficient conditions for wavelet frames in Sobolev space over Locally Compact Abelian Group are given ...
