作者 范丽亚 高淑萍 刘三阳 《运筹学学报》 CSCD 北大核心 2003年第2期57-64,共8页
众所周知,在各种变分不等式问题中,解的存在性是最基础也是最重要的问题之一。本文的目的是在Hilbert空间中研究带有单模糊映射的一般变分不等式解的存在性。此外,还讨论了几种特殊情况。

The stochastic interpretation of Parikh's game logic should not follow the usual pattern of Kripke models, which in turn are based on the Kleisli morphisms for the Giry monad, rather, a specific and more general approach to proba- bilistic nondeterminism is required. We outline this approach together with its probabilistic and measure theoretic basis, in- troducing in a leisurely pace the Giry monad and its Kleisli morphisms together with important techniques for manipu- lating them. Proof establishing specific techniques are given, and pointers to the extant literature are provided. After working through this tutorial, the reader should find it easier to follow the original literature in this and related areas, and it should be possible for her or him to appreciate measure theoretic arguments for original work in the areas of Markov transition systems, and stochastic effectivity func- tions. 展开更多

Algebra Appl. 15 (2016), http: dx.doi.org/10.1142/S0219498816500018], we investigate the latticial counterparts of some results about modules satisfying the conditions (Cll) or (C12). Applications are given to Grothendieck categories and module categories equipped with hereditary torsion theories. 展开更多
