Exponents of Diophantine approximation in dimension two by Michel
Let Θ = (α, β) be a point in R, with 1, α, β linearly independent over Q. We attach to Θ a quadruple Ω(Θ) of exponents which measure the quality of approximation to Θ both by rational points and by rational lines. The two “uniform” components of Ω(Θ) are related by an equation, due to Jarńık, and the four exponents satisfy two inequalities which refine Khintchine’s transference principle. Conve...
متن کاملDiscrete approximation of the Mumford-Shah functional in dimension two
The Mumford-Shah functional, introduced to study image segmentation problems, is approximated in the sense of F-convergence by a séquence of intégral functionals defined on piecewise affine functions. Résumé. La fonctionnelle de Mumford et Shah, proposée pour l'étude du problème de la segmentation d'images, est approchée au sens de la F-convergence par une suite de fonctionnelles intégrales déf...
متن کاملHausdorff dimension and Diophantine approximation
In the present survey paper, we explain how the theory of Hausdorff dimension and Hausdorff measure is used to answer certain questions in Diophantine approximation. The final section is devoted to a discussion around the Diophantine properties of the points lying in the middle third Cantor set.
متن کاملModel Approximation via Dimension Reduction
In the initial stages of refining a mathematical model of a real-world dynamical system, one is often confronted with many more variables and coupled differential equations than one intuitively feels should be sufficient to describe the system. Yet none of the variables may seem so irrelevant as to be excludable nor so dominant as to explain the overall dynamics. Part of the problem might even ...
متن کاملDimension Theory Local and Global
These survey lectures are devoted to a new subject of the large scale dimension theory which was initiated by Gromov as a part of asymptotic geometry. We are going to enter the large scale world and consider some new concepts, results and examples which are parallel in many cases to the corresponding elements of the standard (local) dimension theory. We start our presentation with the motivations.
