We present a new class of oscillons in the (1+1)-dimensional signum-Gordon model. The oscillons periodically move to and fro in the space. They have finite total energy, finite size, and are strictly ...

假设~$\varphi$~是单位球 ~$B_N$~中有一个边界不动点~$e_1$的线性分式自映射, 我们将证明 $$1-\mbox{Re}\, \varphi_1(z)\sim \mbox{Re}(1- z_1)$$ 在~$\overline{B_N}$~上~$e_1$的一个邻域内成立. 利用这个结果我们对~MacCluer~和~Weir的猜测给出一个肯定的回答, 并且可以改进他们所得到的有关复合...

1.引言文中,假定 X 是 Banach 空间,Y 是赋范线性空间。对于 E\subsetY,用 B(E),C(E),cf(E)分别表示 E 的不空的有界,闭,闭凸的子集组。E^o,\partial E 则分别表示 E 的内核(内点全体)及 E 的边界(即\partial E=\bar{E}\E^o)。
令$C$为格序群$A$的某些正元组成的一个容许子集, Gusi\’c 证明$A$可以被赋予一个$C$-\!拓扑使得$A$成为拓扑群. 本文证明$C$-\!拓扑实际上使得$A$成为 拓扑格序群, 给出了Gusi\’c 定理的推广, 并揭示了Gusi\’c $C$-\!群的自然性. 而且, 我们证明$C$-\!拓扑使得任何Archimedean格序向量空间成为$T_2$拓扑格向量空间. 同时, 构造了...
