https://doi.org/10.1007/978-3-319-15741-2The generalized factorization of some classes of 2 ß 2 matrix symbols is determined by reduction to the study of certain scalar non-linear Riemann-Hilbert problems. This method is applied to several types of matrix functions, whose factorization is explicitly obtained.

https://doi.org/10.1007/978-3-030-24124-7For two different examples of positive definitizable operators in Krein spaces we prove regularity of the critical points 0 and ∞. The first example is the Sturm-Liouville operator in ..(ℝ,ρ) with ρ(.) = 007C;x007C;.sgn x. The second example is a difference operator in a Krein space of complex sequences.

C++ Templates for MicrocontrollersLet . be the integration operator defined on .., let .., α > 0, be its positive powers, and let . be a nonsingular . ß . diagonal matrix. The lattices of invariant and hyperinvariant subspaces of the Volterra operator .. ⊗ . defined on .. ⊗ ℂ. are described in geometric terms
