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

从动力系统角度,建义对流扩散方程初边值问题所产生半群一个全局吸引子。

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.

证明后概率关于试半群,从而序贯试与累积试具有相同后概率。
