In this paper, the relations between the uniform topology, weak operator topology and strong operator topology in operator space of Hilbert space and the continuity of several operations are discussed.

讨论了Hilbert空间上全体有界线性算子所成的算子空间上一致拓扑，弱算子拓扑，强算子拓扑之间的关系，以及一些运算在这些拓扑下的连续性。

Wang (1999) discussed it and obtained some properties of the survival probability, the supremum distribution before ruin and the surplus distribution at ruin.

Wang（1999）得到了此模型下生存概率，破产前上界分布及破产时赤字的一些性质；Wang（2001）考虑了破产概率的分解。

We present necessary and sufficient conditions for which there exists A∨_G B and in this case we establish the explicit representation of A∧_G B, where A∨_G B denotes the supremum of A and B associated with the Gudder order.

对任意给定的自伴算子A和B，我们证明了存在A和B关于Gudder序的下(来源：ABC3c论文网www.abclunwen.com)确界A∧_G B并且我们具体地给出了A∧_G B。

Based on the surjection of maximal monotone operators, we prove that some semilinear heat equations with weak Lipschitz nonlinear terms are exactly controllable by L〓 0, T: H〓(Ω control; Based on the critical point theorem of coercive convex functionals, we prove that some parabolic equations with Lipschitz nonlinear terms are globally approximately controllable and finite-dimensional exactly controllable by controls acting on mobile supports, and finally, we extend the results to parabolic equations in R〓.

首先利用极大单调算子的满射原理证明了半线性热方程在较弱Lipschitz条件下可通过L〓0.T；H〓(Ω控制实现精确能控。然后通过构造强制凸泛函并利用其临界点理论证明了带Lipschitz非线性项的抛物型方程可通过作用在在移动支集上的控制来实现整体近似能控与有限维精确能控，最后将整体近似能控与有限维精确能控结论推广到无界区域R〓上。

The existence of solutions for two-point boundary value problem subject to nonlinear second order differential equation with mixed boundary conditions is studied by using topological transversality theorem, and some known results are improved.

现利用拓扑横截定理，考虑了二阶常微分方程两点边值问题在组合边界条件下的解的存在性，对二阶常微分方程两点边值问题所对应的辅助问题作先验界估计，并利用拓扑横截定理，得到了边值问题解的存在性，推广了一些已有结果。

As the true capacity formula for blind-CSI in both transmitter and receiver is hard to obtain, we derive its independent upper bound instead, and establish a close-form expression of the independent bound for any memory order $M$.

由於，在传送端与接收端均无「频道状态资讯」的情况下，管道传输极限的计算相当困难，因此我们转而探讨其「独立上界」。

Second theorem shows that the existence of solution is possible under suitable conditions when the limit of growth of nonlinear term at infinity is an unbounded function.

第二个定理表明当非线性项在无穷远处增长的极限是一个无界函数时在适当条件下这问题仍可能有一个解。

The method attempts to transform the original problem into a series of unconstraint optimization problems.

在这些研究中，均假定在对数障碍函数是严格凸的及解集是非空有界的情况下，证明了方法的全局收敛性。
