13 окт. 2020 г. · Let H,G be Hilbert spaces. Assume that T:H→G is a continuous linear transformation. I want to show that if (xn) is a weakly convergent sequence ...

7 июн. 2014 г. · When X is compact, a sequence of continuous functions converges weakly iff it converges pointwise and is uniformly bounded. But that's not ...

9 июн. 2017 г. · If (un) is bounded in Lp there is a subsequence that converge weakly.

11 февр. 2024 г. · The goal of weak convergence is to have a notion of convergence of measures that can "see" the topology of R, and that's why continuous ...

11 июн. 2018 г. · Proposition: If a sequence converges by the norm then it converges weakly. Proof: |f(xn)−f(x0)|=|f(xn−x0)|⩽||f|||xn−x0||→0 as n→∞.

16 февр. 2014 г. · Let (xn) be a sequence in X that converges weakly to x but which does not converge in norm. Then the sequence (xn−x) converges weakly to 0.

7 апр. 2024 г. · The fundamental reason of "converges weakly*" being weaker is because X is usually a subspace of X′′ (or embedded into X′′), and all these definitions are ...
