Two remarks on weaker connected topologies
It is shown that no generalized Luzin space condenses onto the unit interval and that the discrete sum of א1 copies of the Cantor set consistently does not condense onto a connected compact space. This answers two questions from [2].

متن کاملOutput feedback quantized observer-based synchronization of linear multi-agent systems over jointly connected topologies
The synchronization problem of linear over-actuated multi-agent systems with unmeasurable states is studied in this paper, under both limited communication data rate and switching topology flows. A class of adaptive quantized observer-based encoding–decoding schemes and a class of certainty equivalence principle-based control protocols are proposed. By developing the graph-based space decomposi...
متن کاملWeaker connected and weaker nowhere locally compact topologies for metrizable and similar spaces
We prove that any metrizable non-compact space has a weaker metrizable nowhere locally compact topology. As a consequence, any metrizable non-compact space has a weaker Hausdorff connected topology. The same is established for any Hausdorff space X with a σ -locally finite base whose weight w(X) is a successor cardinal. 2002 Elsevier Science B.V. All rights reserved. AMS classification: Prima...
متن کاملPorous coordination polymers with zeolite topologies constructed from 4-connected building units.
Two novel 3D coordination polymers, Cd(CTC)(H2O).(H2PIP)(0.5)(H2O) (1) with zeolite ABW topology and Cd(CTC).(HIPA) (2) with zeolite BCT topology, have been synthesized by constructing inorganic and organic 4-connected building units and using the organic bases as templates, and the frameworks of and not only expand the original structures of zeolites ABW and BCT, but also exhibit significant a...
