The index of convergence for Boolean matrix A is the same as the index of convergence for the associated digraph D of A.

本论文对布尔矩阵和可约布尔矩阵的幂敛指数的上确界和指数集两个方面中的一系列问题进行了研究。

It is shown that the asymptotically limiting distribution of the residual cusum test statistic is still the sup of a standard Brownian bridge under null hypothesis.

研究表明如果原假设条件成立，则残量累积和统计量的渐近极限分布仍然是一个标准布朗桥的上确界。

We present necessary and sufficient conditions for which there exists A?

B。我们给出了存在A和B关于~*-序的上确界A？

If the supremum belongs to the set, then it is the

如果上确界属于这个集合，则它是这个集合的

Let M be the supremum of the values of f, x nonnegative.

The necessary condition of an important result of the probability that the supremum of a random walk with heavy-tailed increments crosses a curve on a random time interval is presented by using an important property of a general distribution class.

Neutral differential equations with variable sign coefficients are separated into neutral differential equations with positive and negative coefficients by transformation. According to the characteristic of these equations, a real number set with supremum is constructed, and sufficient conditions for oscillation of all solutions to neutral equations with variable sign coefficients are obtained.

通过变换将具有变号系数的中立型微分方程分解为具有正负系数的中立型微分方程；分析具有正负系数中立型微分方程的特征，构造存在上确界的实数集；并对中立型微分方程的解作细致分析，得到了具有变号系数中立型微分方程所有解振动的充分条件。

Moreover, a main inconvenience of mixing assumptions is the difficulty of checking them because the calculation involves the complicated manipulation of taking the supremum over twoσ- algebras.
