Multi-tuple hulls [PDF]

Pacific Journal of Mathematics, 1991
In the paper under review the author (1) presents a unified approach to the study of \(n\)-tuple rational \(A\)- convex hulls and \(n\)-tuple \(A\)-convex hulls and (2) investigates the relationship between these hulls and vector-valued functions and multi-tuple Shilov boundaries of uniform algebras.

Flux Compactifications of String Theory on Twisted Tori

, 2005
Global aspects of Scherk-Schwarz dimensional reduction are discussed and it is shown that it can usually be viewed as arising from a compactification on the compact space obtained by identifying a (possibly non-compact) group manifold G under a discrete ...

A Review on the Energy Storage Mechanisms of Transition Metal Sulfide and Selenide Cathode Materials for Non‐Aqueous Aluminum Batteries

Advanced Energy Materials, EarlyView.
Herein is reviewed the current state of research on transition metal sulfides and selenides (TMSs/TMSes) used as cathode materials for rechargeable aluminum batteries (RABs). The three types of charge storage mechanisms encountered in these materials, as well as contradictions found in the literature, and future research pathways are discussed ...

Tangential Loewner hulls

Annales Fennici Mathematici, 2021
Through the Loewner equation, real-valued driving functions generate sets called Loewner hulls. We analyze driving functions that approach 0 at least as fast as $a (T-t)^r$ as $t \to T$, where $r \in (0, 1/2)$, and show that the corresponding Loewner hulls have tangential behavior at time $T$.

Tailored Ordering Enables High‐Capacity Cathode Materials

Advanced Energy Materials, EarlyView.
A comprehensive first‐principles database is constructed to investigate ordering stability and tendencies in rocksalt‐type LiMO2, aiming to tailor both long‐ and short‐range orderings to encourage favorable rocksalt phase stability and Li diffusion in novel cathode design.

Progress and Challenges in LiMOCl4 and NaMOCl4 (M = Nb, Ta) Oxyhalide Solid Electrolytes for Solid‐State Batteries

Advanced Energy Materials, EarlyView.
LiMOCl4 and NaMOCl4 are attractive solid electrolyte materials due to their wide electrochemical windows, fast ionic conductivities, and ease of synthesis. However, several challenges and unknowns remain including their structure and processability.

Optimal Linear Codes and Their Hulls

Mathematics
The hull of a linear code C is the intersection of C with its dual code. The goal is to study the dimensions of the hulls of optimal binary and ternary linear codes for a given length and dimension.

On Borel Hull Operations

Real Analysis Exchange, 2015
We show that some set-theoretic assumptions (for example Martin's Axiom) imply that there is no translation invariant Borel hull operation on the family of Lebesgue null sets and on the family of meager sets in (in R^n). We also prove that if the meager ideal admits a monotone Borel hull operation, then there is also a monotone Borel hull operation on ...

Redox‐Level Design for High‐Energy‐Density Chloride Electrodes

Advanced Energy Materials, EarlyView.
This study investigates 3d transition metal chlorides with high Li diffusivity using high‐throughput screening and constructs a redox‐level diagram to guide chloride electrode design. Redox‐level tuning of Fe in Li2FeCl4 achieves record‐high energy density for Fe‐based solid‐state batteries, and the strategy is extendable to various electrode material ...
