The concept of quasi-perfect equilibria for games in extensive form is introduced. It is shown that a proper equilibrium of a normal form game induces a quasi-perfect equilibrium in every extensive form game having this normal form. 相似文献

We extend a notion of a lexicographic domination between strategies, introduced for normal form games in Okada (1988), to extensive games via the transformation from the extensive form to the agent normal form. It is shown that lexicographically undominatedness implies subgame perfection of an equilibrium point in extensive games with perfect recall.I am grateful to an anonymous referee for very helpful comments and suggestions. A preliminary draft of this paper was written while I was visiting the MEDS Department of Northwestern University in 1986–87. The warm hospitality of that department is gratefully acknowledged. 相似文献

A facility is called ‘extensive’ if, for purposes of location, it is too large in relation to its environment regarding the activities of interest for it to be considered as a point. The literature on location on a network of ordinary and obnoxious extensive facilities is reviewed. Suggestions are made for possible directions of future research. 相似文献

关于3-正则图的平均亏格 总被引:1,自引:0,他引:1
一个图G的2-因子F是一个使得每个点v在F中的度dF(v)=2的G的生成子图。易知F中的每个圈是点不交的。如果F中每个圈的长度为4,我们说G有四边形2-因子F。我们首先在3-正则图上定义了3种扩张运算,然后讨论这些运算对平均亏格的影响。运用扩张运算,我们研究了含有四边形2-因子的3-正则图的平均亏格,得到了3-正则图的平均亏格与最大亏格之间的关系。 相似文献

In the same way as ‘comprehensive fuzziness’ deals with a-fields of labels, ‘extensive fuzziness’ deals with objects. In this paper, the concept of ‘extensive mapping’ is defined in order to justify the notion of ‘measurable fuzzy function’. This is the natural continuation of the article “Comprehensive fuzziness”, recently published in this Journal. 相似文献

Standard theories of extensive measurement require that all objects to be measured are comparable, and that no object is infinitely or infinitesimally greater than another. The present paper develops a theory that leaves room for infinite and infinitesimal differences, as well as incomparable objects. Our result is analogous to the standard representation and uniqueness theorem of extensive measurement, and only simple and familiar mathematical concepts are assumed. 相似文献
