Tribes of Cubic Partial Cubes
Partial cubes are graphs isometrically embeddable into hypercubes. Three infinite families and a few sporadic examples of cubic partial cubes are known. The concept of a tribe is introduced as means to systematize the known examples and establish relations among them. Efficient methods of computation of tribes are developed and several concrete tribes, that include known, as well as new cubic p...
متن کاملThe Lost Tribes of Charmonium
To illustrate the campaign to extend our knowledge of the charmonium spectrum, I focus on a puzzling new state, X(3872) → ππJ/ψ. Studying the influence of open-charm channels on charmonium properties leads us to propose a new charmonium spectroscopy: additional discrete charmonium levels that can be discovered as narrow resonances of charmed and anticharmed mesons. I call attention to open issu...
متن کاملTree tribes and lower bounds for switching lemmas
We show tight upper and lower bounds for switching lemmas obtained by the action of random p-restrictions on boolean functions that can be expressed as decision trees in which every vertex is at a distance of at most t from some leaf, also called t-clipped decision trees. More specifically, we show the following: 1. If a boolean function f can be expressed as a t-clipped decision tree, then und...
