The elementary diagram of a trivial, weakly minimal structure is near model complete
elementary diagram model complete
2015/9/28
We prove that if M is any model of a trivial, weakly minimal theory,
then the elementary diagram T(M) eliminates quantifiers down
to Boolean combinations of certain existential formulas.
On the structure of finite level and ω-decomposable Borel functions
finite level Borel function countably continuous function Baire class of functions decomposable functions
2012/6/21
We give a full description of the structure under inclusion of all finite level Borel classes of functions, and provide an elementary proof of the well-known fact that not every Borel function can be ...
Let $B$ be a bialgebra, and $A$ a left $B$-comodule algebra in a braided monoidal category $\Cc$, and assume that $A$ is also a coalgebra, with a not-necessarily associative or unital left $B$-action...
Building on recent work by Rippon and Stallard, we explore the intricate structure of the spider's web fast escaping sets associated with certain transcendental entire functions. Our results are expr...
On the structure of ($-\beta$)-integers
structure math
2010/11/12
The $(-\beta)$-integers are natural generalisations of the $\beta$-integers, and thus of the integers, for negative real bases. When $\beta$ is a $(-\beta)$-number, which is the analogue of a Parry nu...
Homotopes of Symmetric Spaces II. Structure Variety and Classification
Homotopes of Symmetric Spaces II Structure
2010/11/19
We classify homotopes of classical symmetric spaces (studied in Part I of this work). Our classification uses the fibered structure of homotopes: they are fibered as symmetric spaces, with flat fibers...
The structure of a the C*-algebra of a locally injective surjection
the C*-algebra locally injective surjection
2010/11/9
We obtain a description of the C*-algebras which can occur as a simple quotient of the C*-algebra of a locally injective surjection on a compact metric space of finite covering dimension.
The theme of the first two sections, is to prepare the framework of how from a "complicated" family of index models I in K_1 we build many and/or complicated structures in a class K_2. The index model...
Multifractal structure of Bernoulli convolutions
Multifractal structure Bernoulli convolutions
2010/11/15
Let $\nu_\lambda^p$ be the distribution of the random series $\sum_{n=1}^\infty i_n \lambda^n$, where $i_n$ is a sequence of i.i.d. random variables taking the values 0,1 with probabilities $p,1-p$. T...
Structure of finite nilspaces and inverse theorems for the Gowers norms in bounded exponent groups
Structure of finite nilspaces inverse theorems the Gowers norms bounded exponent groups
2010/11/11
A result of the author shows that the behavior of Gowers norms on bounded exponent abelian groups is connected to finite nilspaces. Motivated by this, we investigate the structure of finite nilspaces...
The persistent cosmic web and its filamentary structure I: Theory and implementation
Cosmology simulations statistics observations Galaxies formation
2010/12/16
We present DisPerSE, a novel approach to the coherent multi-scale identification of all types of astrophysical structures, and in particular the filaments, in the large scale distribution of matter in...
Renormalization group structure for sums of variables generated by incipiently chaotic maps
Renormalization group chaotic maps
2010/4/7
We look at the limit distributions of sums of deterministic chaotic variables in unimodal maps and find a remarkable renormalization group (RG) structure associated to the operation of increment of su...
Matter-Element Modeling of Parallel Structure and Application about Extension PID Control System
Extension control system matter modeling parallel structure PID predictable algorithm
2007/12/11
This article describes in detail a new method via the extension predictable algorithm of the matter-element model of parallel structure tuning the parameters of the extension PID controller. In compar...
A Theorem on the Structure of the Ring ${\bf A}_{cris}$
Lubin--Tate formal group crystalline period ring
2007/12/10
In this paper, we give a new description for the structure of the $p$-adic period subring $A_{cris}$ using formal groups.
On the Quasi-Hopf structure of deformed double Yangians
Quasi-Hopf structure deformed double Yangians
2010/10/29
We construct universal twists connecting the centrally extended double Yangian DY(sl(2))_c with deformed double Yangians DY_r(sl(2))_c, thereby establishing the quasi-Hopf structures of the latter.
