Variation on a theme of Schütte
Let ≺ be a primitive recursive well-ordering on the natural numbers and assume that its order-type is greater than or equal to the prooftheoretic ordinal of the theory T. We show that the proof-theoretic strength of T is not increased if we add the negation of the statement which formalizes transfinite induction along ≺.
متن کاملOne Variation on Lloyd's Theme
One random spin2 XY chain that after Jordan-Wigner fermionization reduces to the extended Lloyd’s model is considered. The random-averaged one-fermion Green functions have been calculated exactly that yields thermodynamics of the spin model. PACS codes: 75.10.-b
متن کاملA Variation on a Theme of Caffarelli and Vasseur
Recently, using DiGiorgi-type techniques, Caffarelli and Vasseur [1] showed that a certain class of weak solutions to the drift diffusion equation with initial data in L gain Hölder continuity provided that the BMO norm of the drift velocity is bounded uniformly in time. We show a related result: a uniform bound on BMO norm of a smooth velocity implies uniform bound on the C norm of the solutio...
متن کاملVariation on an Src-like Theme
The modularity of protein architecture and the diversity of protein domains hint at a vast combinatorial richness. But evolution appears to have been relatively conservative about selecting new combinations. When a particular grouping of domains within a polypeptide chain can perform a concerted function, that combination tends to reappear in multiple genomic contexts. In other words, once a mo...
