Z Is Universal

چکیده
We use order zero maps to express the Jiang-Su algebra Z as a universal C∗-algebra on countably many generators and relations, and we show that a natural deformation of these relations yields the stably projectionless algebra W studied by Kishimoto, Kumjian and others. Our presentation is entirely explicit and involves only ∗-polynomial and order relations.

Filters and the Weakly Almost Periodic Compactification of a Semitopological Semigroup
Let $S$ be a semitopological semigroup. The $wap-$ compactification of semigroup S, is a compact semitopological semigroup with certain universal properties relative to the original semigroup, and the $Lmc-$ compactification of semigroup $S$ is a universal semigroup compactification of $S$, which are denoted by $S^{wap}$ and $S^{Lmc}$ respectively. In this paper, an internal construction of ...
متن کاملUniversal Z-lattices of Minimal Rank
Let UZ(n) be the minimal rank of n-universal Z-lattices, by which we mean positive definite Z-lattices which represent all positive Z-lattices of rank n. It is a well known fact that UZ(n) = n + 3 for 1 ≤ n ≤ 5. In this paper, we determine UZ(n) and find all n-universal lattices of rank UZ(n) for 6 ≤ n ≤ 8.
متن کاملImproved Estimate on the Number of Bound States of Negatively Charged Bosonic Atoms
It is shown that the number of bound states of an atom whose \electrons" satisfy bosonic symmetry conditions is bounded above by C (log Z) where, and C are constants, the nuclear charge Z > Z for some constant Z and the number of \electrons" N satisiies N > (1+)Z +1 with > 0. The constant is universal, but Z depends upon and C is inversely proportional to a power of .
متن کاملarXiv : 0906 . 2450 ON SOME UNIVERSAL SUMS OF GENERALIZED POLYGONAL NUMBERS
For m = 3, 4, . . . those pm(x) = (m − 2)x(x − 1)/2 + x with x ∈ Z are called generalized m-gonal numbers. Recently the second author studied for what values of positive integers a, b, c the sum ap5 + bp5 + cp5 is universal over Z (i.e., any n ∈ N = {0, 1, 2, . . . } has the form ap5(x) + bp5(y) + cp5(z) with x, y, z ∈ Z). In this paper we proved that p5 + bp5 + 3p5 (b = 1, 2, 3, 4, 9) and p5 +...
متن کاملUniversal Mixed Sums of Squares and Triangular Numbers
In 1997 Ken Ono and K. Soundararajan [Invent. Math. 130(1997)] proved that under the generalized Riemann hypothesis any positive odd integer greater than 2719 can be represented by the famous Ramanujan form x 2 + y 2 + 10z 2 , equivalently the form 2x 2 + 5y 2 + 4T z represents all integers greater than 1359, where T z denotes the triangular number z(z + 1)/2. Given positive integers a, b, c we...
متن کاملUniversal relation between Green’s functions in random matrix theory
We prove that in random matrix theory there exists a universal relation between the one-point Green’s function G and the connected twopoint Green’s function Gc given by NGc(z,w) = ∂ ∂z∂w log(( G(z)−G(w) z−w ) + irrelevant factorized terms. This relation is universal in the sense that it does not depend on the probability distribution of the random matrices for a broad class of distributions, ev...
