  • On the Koplienko Spectral Shift Function. I. Basics 
    Gesztesy, F.; Pushnitski, A.; Simon, B. (Журнал математической физики, анализа, геометрии, 2008)
    We study the Koplienko Spectral Shift Function (KoSSF), which is distinct from the one of Krein (KrSSF). KoSSF is defined for pairs A,B with (A - B) is in I₂, the Hilbert{Schmidt operators, while KrSSF is defined for pairs ...
  • Schrödinger Operators with Purely Discrete Spectrum 
    Simon, B. (2009)
    We prove that −Δ+V has purely discrete spectrum if V ≥ 0 and, for all M, |{x | V (x)<M}| < ∞ and various extensions.
