✦ Synopsis

Finite element generation methods, such as Delaunay, allow the meshing of shapes from a set of nodes. These nodes must previously exist. The authors present a simple, fast and reliable method to generate them in an unstructured way in N-dimensional space. Its main characteristic is to easily allow variation of the node density by introducing a density function, either analytical or discretized. This function can also be anisotropic. Some nodes can have a pre-fixed position. Inner lines and holes can also be specified in the domain to be meshed. Generated nodes are to be connected according to triangles in 2D and tetrahedrals in 3D.

## Abstract We prove a factorization theorem for functions in __H__ ^1^(ℝ^__n__^ ) using generalized Morrey spaces. As a corollary of our result we show that if the commutator of Coifman, Rochberg and Weiss [__b__ , __T__ ] is bounded on the generalized Morrey spaces, then __b__ is a __BMO__ functi
