    Lanczos Tridiagonalization and Core Problems

  • Original language description

    The paper "C.C. Paige, Z. Strakoš: Core problems in linear algebraic systems (SIAM J. Matrix Anal. Appl. 27 (2006), pp. 861-875)" presents a core problem formulation of orthogonally invariant linear approximation problems Ax ~ b, that extracts the necessary and sufficient information for solving the originál problem. Our contribution derives the fundamental characteristics of the core problem from the known relationship between the Golub-Kahan bidiagonalization and the Lanczos tridiagonalization.

    Lanczošova třídiagonalizace a core problémy

  • Czech description

    V článku "C.C. Paige, Z. Strakoš: Core problems in linear algebraic systems (SIAM J. Matrix Anal. Appl. 27 (2006), pp. 861-875)" je definován a popsán pojem core problému v ortogonálně invariantních aproximačních úlohách Ax ~ b, který extrahuje nutné a postačující informace pro řešení uvedené úlohy. V tomto článku odvodíme základní vlastnosti core problému ze známých vztahů mezi Lanczošovou třídiagonalizací a Golub-Kahanovou bidiagonalizací.
