半群

Abstract： Bipartite graphs with P-regular endomorphism monoids are characterized.P-regularity of the endomorphism monoid of lexicographic product of graphs is discussed.

摘要 ：刻划了具有P-正自同态幺半群二分图，讨论了字典序积图自同态幺半群P-正.

This paper establishes a global attractor of hemigroup produced by the initial boundary value problem of generalized convection and expansion equation.

动力系统角度,建立了广义对流散方程初边值问题所产生半群全局吸引子。

It proves that the posterior probability about experiments makes up hemigroup then proves that the posterior probability of the order experiments and the accumulation experiments are the same.

证明了后验概率关于试验构成半群,而序贯试验与累积试验具有相同后验概率。
