A note on polynomial approximation in Sobolev spaces
Résumé: Pour des domaines étoilés on donne des nouvelles bornes sur les constants dans les inégalités de Jackson pour les espaces de Sobolev. Pour des domaines convexes, les bornes ne dépendent pas de l’excentricité. Pour des domaines non-convexes ayant un point rentrant, les bornes sont uniformes par rapport à l’angle extérieur. L’outil central est un nouvel opérateur de projection sur l’espac...
متن کاملA Note on the Degree of Polynomial Approximation*
Let C be a rectifiable Jordan curve of the finite z plane. We shall say that a function f(z) belongs to the class Lip (C, j , a) if ƒ (z) is regular in the limited region bounded by C (which we shall call the interior of C), if f{z) is continuous in the corresponding closed region, and if the jth. derivative of f(z) is also continuous in this closed region and satisfies a Lipschitz condition wi...
متن کاملA Note on Strong Jordan Separation
We establish a strengthening of Jordan separation, to the setting of maps f : X → S, where X is not necessarily a manifold, and f is not necessarily injective.
متن کاملA Note on the Jordan Canonical Form
A proof of the Jordan canonical form, suitable for a first course in linear algebra, is given. The proof includes the uniqueness of the number and sizes of the Jordan blocks. The value of the customary procedure for finding the block generators is also questioned. 2000 MSC: 15A21. The Jordan form of linear transformations is an exceeding useful result in all theoretical considerations regarding...
متن کاملA Note on Belief Structures and S-approximation Spaces
We study relations between evidence theory and S-approximation spaces. Both theories have their roots in the analysis of Dempsterchr('39')s multivalued mappings and lower and upper probabilities, and have close relations to rough sets. We show that an S-approximation space, satisfying a monotonicity condition, can induce a natural belief structure which is a fundamental block in evidence theory...
