{ 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 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 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 کاملLogic and Music in Plato’s Phaedo
This paper aims to achieve a better understanding of what Socrates means by “sumfvne›n” in the sections of the Phaedo in which he uses the word, and how its use contributes both to the articulation of the hypothetical method and the proof of the soul’s immortality. Section I sets out the well-known problems for the most obvious readings of the relation, while Sections II and III argue against t...
متن کاملD - module lecture note 16
Let f : X → Y be a morphism of smooth varieties. Then we already know that the (higher) pull-back of a quasicoherent sheaf is quasicoherent. Since a pull-back as a D-module and as an O-module are the same (with some shift,) it is still true for a D-module case. (One might doubt it since in each case the category on which Lif∗ is defined is different, but we can compose a forgetful functor D(Mod...
