The CLEO-c research program will include studies of leptonic, semileptonic and hadronic charm decays, searches for exotic and gluonic matter, and test for physics beyond the Standard Model. The experiment and the CESR accelerator were modified to efficiently operate at center-of-mass energies between 3 and 5 GeV. Data at the ψ(3770) resonance were recorded with the CLEO-c detector in September ...

Kuratowski’s 14-set theorem says that in a topological space, 14 is the maximum possible number of distinct sets which can be generated from a fixed set by taking closures and complements. In this article we consider the analogous questions for any possible subcollection of the operations {closure, complement, interior, intersection, union}, and any number of initially given sets. We use the al...
