Factorization of symplectic matrices into elementary factors
Björn Ivarsson, Frank Kutzschebauch, Erik Løw
We prove that a symplectic matrix with entries in a ring with Bass stable rank one can be factored as a product of elementary symplectic matrices. This also holds for null-homotopi…
On the number of factors in the unipotent factorization of holomorphic mappings into
Björn Ivarsson, Frank Kutzschebauch
We estimate the number of unipotent elements needed to factor a null-homotopic holomorphic map from a finite dimensional reduced Stein spaces into .
Holomorphic factorization of mappings into SL_n(C)
Björn Ivarsson, Frank Kutzschebauch
We solve Gromov's Vaserstein problem. Namely, we show that a null-homotopic holomorphic mapping from a finite dimensional reduced Stein space into SL_n(C) can be factored into a fi…
An interpolation theorem for proper holomorphic embeddings
Franc Forstneric, Bjorn Ivarsson, Frank Kutzschebauch +1
Given a Stein manifold X of dimension n>1, a discrete sequence a_j in X, and a discrete sequence b_j in C^m where m > [3n/2], there exists a proper holomorphic embedding of X into…
