Numberings and Randomness,lasses contained in the Martin-Löf random reals do not even have an effective numbering, nor do the left-c.e. reals satisfying a fixed randomness constant. For . classes contained in the class of reals satisfying a fixed randomness constant, we prove that at least an effective numbering exists.

Graph States and the Necessity of Euler Decomposition, of graph states. We then introduce a new equation, for the Euler decomposition of the Hadamard gate, and demonstrate that Van den Nest’s theorem—locally equivalent graphs represent the same entanglement—is equivalent to this new axiom. Finally we prove that the Euler decomposition equation is not derivable from the existing axioms.

First-Order Universality for Real Programs,s that, to compute a given function, it is in fact always possible to find a program with a faithful denotation. We briefly indicate how our proof extends to show that functions taken from a large class of computable, first-order . functions in several arguments are definable.

Immunity for Closed Sets,t the immune degrees in the Medvedev lattice of closed sets forms a filter. We show that for any . class . with no computable element, there is a . class . which is not immune and has no computable element, and which is Medvedev reducible to .. We show that any random closed set is immune.

Cutting Planes and the Parameter Cutwidth,or . based on the sum cutwidth plus rank. Specifically, the cutwidth+rank of .. is bound by a constant . (depending on . only) iff . has no (infinite) models. This result may be seen as a relative of various gap theorems extant in the literature.
