HIGHLIGHTS
- who: Amu00edlcar Branquinho from the Departamento de Matemu00e1tica, Universidade de, Madrid, Spain have published the article: Bidiagonal factorization of tetradiagonal matrices and Darboux transformations, in the Journal: (JOURNAL)
- what: The corresponding monic recursion matrix T J P was considered and the authors show that this recursion matrix was a positive matrix whenever the parameters u03b1, u03b2 lay in the strip given by |u03b1 - u03b2| and amp;lt; 1. The authors show these regions in the following figure A. Branquinho et_al Lemma 2 (i) For the sequence {u03b1n }nu2208N of the first bidiagonal factorization, the authors . . .
