黎斯空间中Carleman算子的序性质

设G是一个赋范的黎斯空间,F是一个黎斯空间,作者证明:受Carleman算子控制的算子也是Carleman算子:序有界的Carleman算子是序闭的;如果T:G→F是Carleman算子.且|T|存在,则|T|也是Carleman算子。

完备格上的张量积

本文讨论了完备格上张量积的一个有意义的性质:A、B是完备的Heyting代数,当且仅当A与B的张量积是完备的Heyting代数。     

The Comparative Statics of Constrained Optimization Problems

This paper develops and applies some new results in the theory of monotone comparative statics. Let f be a real‐valued function defined on R^l and consider the problem of maximizing f(x) when x is constrained to lie in some subset C of R^l. We develop a natural way to order the constraint sets C and find the corresponding restrictions on the objective function f that guarantee that optimal solutions increase with the constraint set. We apply our techniques to problems in consumer, producer, and portfolio theory. We also use them to generalize Rybcsynski's theorem and the LeChatelier principle.
