A Note on D-spaces
We introduce notions of nearly good relations and N-sticky modulo a relation as tools for proving that spaces are D-spaces. As a corollary to general results about such relations, we show that Cp(X) is hereditarily a D-space whenever X is a Lindelöf Σ-space. This answers a question of Matveev, and improves a result of Buzyakova, who proved the same result for X compact. We also prove that if a ...
متن کامل{ 1{ Note on D Mesons
The new experimental results on charm meson decays reported in this edition are predominantly from CLEO II at the e + e ? storage ring CESR and from xed-target experiments, especially photoproduction experiment E687 at Fermilab. The rst results from the BES experiment, operating at an e + e ? center-of-mass energy of 4.0 GeV, also appear in this edition. BES has measured the branching fractions...
متن کاملA Note on Interaction and Incompleteness D .
The notion of interaction and interaction machines, developed by Peter Wegner, includes the comparison between incompleteness of interaction machines and Gödel incompleteness. However, this comparison is not adequate, because it combines different notions and different sources of incompleteness. In particular, it merges syntactic with two senses of semantic completeness, and results about truth...
متن کاملA Note on a Problem Posed by D . E . Knuth
We resolve a conjecture proposed by D.E. Knuth concerning a recurrence arising in the satisfiability problem. Knuth’s recurrence resembles recurrences arising in the analysis of tries, in particular PATRICIA tries, and asymmetric leader election. We solve Knuth’s recurrence exactly and asymptotically, using analytic techniques such as the Mellin transform and analytic depoissonization.
متن کاملA Note on D–brane — Anti–D–brane Interactions in Plane Wave Backgrounds
We study aspects of the interaction between a D–brane and an anti-D–brane in the maximally supersymmetric plane wave background of type IIB superstring theory, which is equipped with a mass parameter μ. An early such study in flat spacetime (μ = 0) served to sharpen intuition about D–brane interactions, showing in particular the key role of the “stringy halo” that surrounds a D–brane. The halo ...
