We prove that the tolerance lattice TolA of an algebra A from a congruence modular variety V is 0-1 modular and satisfies the general disjointness property. If V is congruence distributive, then the lattice Tol A is pseudocomplemented. If V admits a majority term, then Tol A is 0-modular.

主要研究了自然扩充中,熵对、极大零熵因子、一致正熵和完全正熵等与熵有关的动力学性质,以及不交性和弱不交性等与乘积有关的动力学性质.应用这些性质,构造了自身和其自然扩充之间具有严格的中间因子的极小拓扑动力系统. 相似文献

引入了Hilbert空间H中广义框架的非交性、强非交性,讨论了它们的一些性质;并且引入了保非交算子、强保非交算子,证明了酉算子、可逆算子是强保非交算子,下有界算子、余等距算子是保非交算子. 相似文献

The duals of and with respect to disjointness preserving groups are characterized. A. Plessner's result (1929) about the translation group is extended. A Wiener-Young type theorem for disjointness preserving groups is obtained.

如果一个酉系统有完全的游荡向量,那么它的框架向量可以参数化.这有利于研究每种类型的框架向量和它们的相互关系.该文主要给出了一个酉系统的框架向量的参数化结果,无论这个酉系统是否有完全的游荡向量,其应用是:给出了两个框架向量弱相交、相交和强相交的等价条件. 相似文献

We construct an invertible disjointness preserving operator on a normed lattice such that is not disjointness preserving.
