Dilatation structures I. Fundamentals
نویسنده
چکیده
A dilatation structure is a concept in between a group and a differential structure. In this article we study fundamental properties of dilatation structures on metric spaces. This is a part of a series of papers which show that such a structure allows to do non-commutative analysis, in the sense of differential calculus, on a large class of metric spaces, some of them fractals. We also describe a formal, universal calculus with binary decorated planar trees, which underlies any dilatation structure. AMS MSC 2000: 20F65; 22A10; 51F99

متن کاملDilatation structures with the Radon-Nikodym property
The notion of a dilatation structure stemmed out from my efforts to understand basic results in sub-Riemannian geometry, especially the last section of the paper by Belläıche [2] and the intrinsic point of view of Gromov [5]. In these papers, as in other articles devoted to sub-Riemannian geometry, fundamental results admiting an intrinsic formulation were proved using differential geometry too...
متن کاملStable Banach Spaces and Banach Space Structures, I: Fundamentals
We study model theoretical stability for Banach spaces and structures based on Banach spaces, e.g., Banach lattices or C∗-algebras. We prove that a theory is stable if and only if the following condition is true in every model E of the theory: If (ām ) and (b̄n) are bounded sequences in Ek and El (respectively) and R : Ek × El → R is definable, then there exist subsequences (āmi ) and (b̄n j ) su...

A 25-year-old woman (gravida 2, abortion 1) was admitted to Ghaem Hospital affiliated to Mashhad University of Medical Sciences at 24th week of gestation. Her chief complaint was bloody show. She had a history of incompetent cervix, with premature labor at 22nd week of gestation. She was hospitalized with 4 cm dilatation and 50% effacement of cervix at 24th week of gestation. Following bed rest...
متن کاملIntegrable Open Spin Chains in Defect Conformal Field Theory
We demonstrate that the one-loop dilatation generator for the scalar sector of a certain perturbation of N = 4 Super Yang-Mills with fundamentals is the Hamiltonian of an integrable spin chain with open boundary conditions. The theory is a supersymmetric defect conformal field theory (dCFT) with the fundamentals in hypermultiplets confined to a codimension one defect. We obtain a K-matrix satis...
