巴拿赫空间上的有界拓扑及其在经济理论中的一些应用:评论

Bounded topologies on Banach spaces and some of their uses in economic theory: a review

Andrew J. Wrobel

摘要:

综述了实巴拿赫空间上拓扑T的有界和凸有界变体bT和cbT的已有结果。重点讨论了对偶巴拿赫空间P* 上的弱 * 和Mackey拓扑T = w(P *,P)和T = m(P*,P)的情形.已知凸有界Mackey拓扑cbm(P*,P)与m(P*,P)相同。对于bm(P*,P),它被证明严格强于m(P*,P),或者等价地,不是向量拓扑(除非P是自反的)。指出了有界Mackey拓扑和有界弱 * 拓扑在经济理论及其应用中的一些用途。本文还讨论了一般巴拿赫空间Y上的有界弱拓扑和紧弱拓扑bw(Y,Y*)和kw(Y,Y*),以及它们的凸变体cbw和ckw。

英文摘要:

Known results are reviewed about the bounded and convex bounded variants, bT and cbT, of a topology T on a real Banach space. The focus is on the cases of T = w(P*, P) and of T = m(P*, P), which are the weak* and the Mackey topologies on a dual Banach space P*. The convex bounded Mackey topology, cbm(P*, P), is known to be identical to m(P*, P). As for bm(P*, P), it is conjectured to be strictly stronger than m(P*, P) or, equivalently, not to be a vector topology (except when P is reflexive). Some uses of the bounded Mackey and the bounded weak* topologies in economic theory and its applications are pointed to. Also reviewed are the bounded weak and the compact weak topologies, bw(Y, Y*) and kw(Y, Y*), on a general Banach space Y, as well as their convex variants (cbw and ckw).
