  • Daugavet Centers 
    Bosenko, T.; Kadets, V. (Журнал математической физики, анализа, геометрии, 2010)
    An operator G: X → Y is said to be a Daugavet center if ||G + T|| = ||G|| + ||T|| for every rank-1 operator T: X → Y . The main result of the paper is: if G: X →! Y is a Daugavet center, Y is a subspace of a Banach space ...
  • Dominated Convergence and Egorov Theorems for Filter Convergen 
    Kadets, V.; Leonov, A. (Журнал математической физики, анализа, геометрии, 2007)
    We study the filters, such that for convergence with respect to this filters the Lebesgue dominated convergence theorem and the Egorov theorem on almost uniform convergence are valid (the Lebesgue filters and the Egorov ...
  • Narrow Operators on Bochner L₁-Spaces 
    Boyko, K.; Kadets, V.; Werner, D. (Журнал математической физики, анализа, геометрии, 2006)
    Narrow operators on L₁(μ;X)-spaces are studied. We present a sufficient criterion for such an operator to be narrow that resembles the characterization on narrow operators on L₁(μ) and show that the criterion is necessary ...
  • Radon-Nikodým Theorems for Multimeasures in Non-Separable Spaces 
    Cascales, B.; Kadets, V.; Rodríguez, J. (Журнал математической физики, анализа, геометрии, 2013)
    We prove two Radon-Nikodým theorems for multimeasures using setvalued Pettis integrable derivatives. The first one works for dominated strong multimeasures taking convex compact values in a locally convex space. The second ...
  • The Schur ℓ₁ Theorem for Filters 
    Lopez, A. Aviles; Salinas, B. Cascales; Kadets, V.; Leonov, A. (2007)
    We study the classes of filters F on N such that the weak and strong F-convergence of sequences in ℓ₁ coincide. We study also an analogue of ℓ₁ weak sequential completeness theorem for lter convergence.
