Remote Sensing, 2015 Normally, polarimetric SAR classification is a high-dimensional nonlinear mapping problem. In the realm of pattern recognition, sparse representation is a very efficacious and powerful approach.

Stein structures and holomorphic mappings
Mathematische Zeitschrift, 2007 We prove that every continuous map from a Stein manifold X to a complex manifold Y can be made holomorphic by a homotopic deformation of both the map and the Stein structure on X.

An increasing sequence of stein manifolds whose limit is not Stein
Mathematische Annalen, 1976 This question was raised in 1933 by Behnke-Thullen [2] in the case when M is an open subset of complex Euclidean space. In the same paper they solved this problem for various special domains M. The problem was solved affirmatively for arbitrary open subsets M in IF" by Behnke-Stein [1, 1938]. K.

The topology of Stein fillable manifolds in high dimensions II [PDF]
, 2015 We continue our study of contact structures on manifolds of dimension at least five using complex surgery theory. We show that in each dimension 2q+1 > 3 there are 'maximal' almost contact manifolds to which there is a Stein cobordism from any other (2q ...

Holomorphic submersions from Stein manifolds [PDF]
Annales de l'Institut Fourier, 2004 We establish the homotopy classification of holomorphic submersions from Stein manifolds to Complex manifolds satisfying an analytic property introduced in the paper. The result is a holomorphic analogue of the Gromov--Phillips theorem on smooth submersions.

The union problem on complex manifolds
International Journal of Mathematics and Mathematical Sciences, 2002 Let Ω be a relatively compact subdomain of a complex manifold, exhaustable by Stein open sets. We give a necessary and sufficient condition for Ω to be Stein, in terms of L2 -estimates for the ∂¯-operator, equivalent to the condition of Markoe (1977) and

Compact Stein surfaces with boundary as branched covers of $\B^4$ [PDF]
, 2000 We prove that Stein surfaces with boundary coincide up to orientation preserving diffeomorphisms with simple branched coverings of $\B^4$ whose branch set is a positive braided surface. As a consequence, we have that a smooth oriented 3-manifold is Stein

Approximation and extension of Hermitian metrics on holomorphic vector bundles over Stein manifolds
Comptes Rendus. MathématiqueWe show that a singular Hermitian metric on a holomorphic vector bundle over a Stein manifold which is negative in the sense of Griffiths (resp. Nakano) can be approximated by a sequence of smooth Hermitian metrics with the same curvature negativity.
