    A Theorem of the Alternatives for the Equation Ax + B|x| = b

  • Original language description

    The following theorem is proved: given square matrices A, D of the same size, D nonnegative, then either the equation Ax + B|x| = b has a unique solution for each B with |B| le D and for each b, or the equation Ax + B0|x| = 0 has a nontrivial solution for some matrix B0 of a very special form, |B0| le D; the two alternatives exclude each other.....

    Věta o alternativách pro rovnici Ax+B|x|=b

  • Czech description

    Je dokázána následující věta: jsou-li dány čtvercové matice A, D stejného řádu, D nezáporná, potom buď rovnice Ax+B|x|=b má pro každou matici B takovou, že |B|<=D a pro každou pravou stranu b právě jedno řešení, nebo rovnice Ax + B_0|x| = 0 má netriviální řešení pro jistou matici B_0 velmi speciálního tvaru, |B_0| <= D; tyto dvě alternativy se vzájemně vylučují....
