چکیده

We consider the Sobolev space X = W s,p(Sm;Sk−1). We prove the existence of a robust distributional Jacobian Ju for u ∈ X provided sp ≥ k−1; this generalizes a result of Bourgain, Brezis and the second author [10], where the case m = k is considered. In the critical case where sp = k − 1, we identify the image of the map X 3 u 7→ Ju. This extends a result of Alberti, Baldo and Orlandi [2] for s = 1 and p = k−1. We also present a new, analytical, dipole construction method.

The Characterization of the Regularity of the Jacobian Determinant in the framework of Potential spaces

We give necessary and suucient conditions on the parameters s 1 ; s 2 such that the Jacobian determinant extends to a bounded operator from _ H s1 p1 _ H s2 p2 : : : _ H sm pm into Z 0. Here all spaces are deened on R n and 2 m n. In almost all cases the regularity of the Jacobian determinant is calculated exactly.

A Note on the Jacobian Conjecture

In this paper we consider the Jacobian conjecture for a map f of complex affine spaces of dimension n. It is well-known that if f is proper then the conjecture will hold. Using topological arguments, specifically Smith theory, we show that the conjecture holds if and only if f is proper onto its image.

Applying design ideas to promote security of urban spaces

Security is one of the most critical factors affecting the quality of urban spaces. Nowadays, most of these spaces have become merely pathways with neither social life nor sense of belonging to it. Insufficiency of public surveillance along with weak sense of control and surveillance results in spaces with high crime rate. In the late 60s and early 70s, high crime statistics in open urban space...
