Über ein Interpolationsproblem
Über eine elementare Fläche
In vorliegender Arbeit wird die Konstruktion eines Flächenpflasters behandelt. Die Hauptgeneratrizen dieses Pflasters sind Kurvensegmente, deren Konstruktion in der Arbeit [J. Matušů, J. Novák: Über ein Interpolationsproblem. Apl. mat. 2(1976)] entwickelt wurde.
Über einen Interpolations-Algorithmus und gewisse andere Formeln, die in der Theorie der Interpolation durch rationale Funktionen bestehen.

UR Birkhoff interpolation with rectangular sets of derivatives
In this paper we characterize the regular UR Birkhoff interpolation schemes ( uniform, rectangular sets of nodes) with rectangular sets of derivatives, and beyond.

Weakly Increasing Zero-Diminishing Sequences
The following problem, suggested by Laguerre’s Theorem (1884), remains open: Characterize all real sequences {μk} k=0...∞ which have the zero-diminishing property; that is, if k=0...n, p(x) = ∑(ak x^k) is any P real polynomial, then k=0...n, p(x) = ∑(μk ak x^k) has no more real zeros than p(x). In this paper this problem is solved under the additional assumption of a weak growth condition on the sequence {μk} k=0...∞, namely lim n→∞ | μn |^(1/n) < ∞. More precisely, it is established that...
