Lifting default for S1-valued maps
Let ' 2 C1([0, 1]N ,R). When 0 < s < 1, p 1 and 1 sp < N , the W s,p-semi-norm |'|W s,p of ' is not controlled by |g|W s,p , where g := eı' [3]. [This question is related to existence, for S1-valued maps g, of a lifting ' as smooth as allowed by g.] In [4], the authors suggested that |g|W s,p does control a weaker quantity, namely |'|W s,p+W 1,sp . Existence of such control is due to J. Bourg...
متن کاملLifting of S-valued Maps in Sums of Sobolev Spaces
We describe, in terms of lifting, the closure of smooth S-valued maps in the space W ((−1, 1) ;S). (Here, 0 < s <∞ and 1 ≤ p <∞.) This description follows from an estimate for the phase of smooth maps: let 0 < s < 1, let φ ∈ C∞([−1, 1] ;R) and set u = e. Then we may split φ = φ1 + φ2, where the smooth maps φ1 and φ2 satisfy (∗) |φ1|W s,p ≤ C|u|W s,p and ‖∇φ2‖ Lsp ≤ C|u| p W s,p . (∗) was proved...
متن کاملExtension theorems for vector valued maps
We revisit studies on extension of Lipschitz maps and obtain new results about extension of displacements of bounded strain tensors. These questions are of interest in elasticity theory, optimal designs, as well as in functional analysis. Résumé Nous discutons l’extension d’applications Lipschitziennes et donnons, entre autres, une nouvelle démonstration d’un théorème de Schönbeck. Puis nous ét...
متن کاملOn measure concentration of vector valued maps
In this work, we study concentration properties for vector valued maps. In particular, we describe inequalities which capture the exact dimensional behavior of Lipschitz maps with values in Rk. To this task, we study in particular a domination principle for projections which might be of independent interest. We further compare our conclusions to earlier results by Pinelis in the Gaussian case, ...
متن کاملOperator-Valued Bochner Theorem, Fourier Feature Maps for Operator-Valued Kernels, and Vector-Valued Learning
This paper presents a framework for computing random operator-valued feature maps for operator-valued positive definite kernels. This is a generalization of the random Fourier features for scalar-valued kernels to the operator-valued case. Our general setting is that of operator-valued kernels corresponding to RKHS of functions with values in a Hilbert space. We show that in general, for a give...
