A note on an expansion formula with application to nonlinear DAE's
Matthias Stiefenhofer
In [DL] systems of differential polynomials are investigated with respect to properties of Artin approximation type. The key tool in [DL] is an extended version of a formula by Hur…

An analytic bifurcation principle for Fredholm operators
Matthias Stiefenhofer
Smooth Equations of the form G[z]=0 are investigated in Banach spaces with the aim of continuing the basic solution G[0]=0 to a solution curve of G[z]=0 with the implicit function…

Direct sum condition and Artin Approximation in Banach spaces
Matthias Stiefenhofer
The system of undetermined coefficients of a bifurcation problem G[z]=0 in Banach spaces is investigated for proving the existence of families of solution curves by use of the impl…
