IntroductionCurrently the problem of transferring results of algebraic topology to discrete objects and, in particular, to various categories of digraphs and graphs, is widely investigated. The main technical tools are given by the homotopy theory and various homology theories. We present the basic methods of algebraic topology in graph theory and describe relations between continious and discr...
AbstractI am going to make elementary discussions on some random recursive systems in probability theory. These systems have very simple forms, for which most mathematical questions remain yet unanswered.Shi Zhan 施展Academy of Mathematics and System ScienceChinese Academy of Sciences施展,中国科学院数学与系统科学研究院研究员。他本科毕业于中国科学技术大学数学系,在巴黎第六大学获得数学硕士和博士...
