Webバナッハ=アラオグルの定理(バナッハ=アラオグルのていり、英: Banach–Alaoglu theorem)あるいはアラオグルの定理として知られる定理は、ノルム空間Vの共役空間V*の閉単位球が*弱位相関してコンパクトになるという定理である[1]。 この定理の背景を簡単に述べると、関数解析学では無限次元のノルム空間Vを多用し、Vやその共役空間V*の … Before proving the proposition above, it is first shown how the Banach–Alaoglu theorem follows from it (unlike the proposition, Banach–Alaoglu assumes that is a topological vector space (TVS) and that is a neighborhood of the origin). Proof that Banach–Alaoglu follows from the proposition above See more In functional analysis and related branches of mathematics, the Banach–Alaoglu theorem (also known as Alaoglu's theorem) states that the closed unit ball of the dual space of a normed vector space is compact in … See more A special case of the Banach–Alaoglu theorem is the sequential version of the theorem, which asserts that the closed unit ball of the dual space of a separable normed vector space is sequentially compact in the weak-* topology. In fact, the weak* topology on … See more The Banach–Alaoglu may be proven by using Tychonoff's theorem, which under the Zermelo–Fraenkel set theory (ZF) axiomatic framework is equivalent to the axiom of choice. … See more According to Lawrence Narici and Edward Beckenstein, the Alaoglu theorem is a "very important result - maybe the most important fact … See more If $${\displaystyle X}$$ is a vector space over the field $${\displaystyle \mathbb {K} }$$ then $${\displaystyle X^{\#}}$$ will denote the algebraic dual space of $${\displaystyle X}$$ and … See more Consequences for normed spaces Assume that $${\displaystyle X}$$ is a normed space and endow its continuous dual space See more • Bishop–Phelps theorem • Banach–Mazur theorem • Delta-compactness theorem • Eberlein–Šmulian theorem – Relates three different kinds of weak compactness in a Banach space See more WebMay 26, 2024 · Olá, pessoal!
