    Cesaro bounded operators in Banach spaces 
    Bermúdez, Teresa; Bonilla, Antonio; Muller, Vladimir; Peris Manguillot, Alfredo (Springer-Verlag, 2020-03)
    [EN] We study several notions of boundedness for operators. It is known that any power bounded operator is absolutely Cesaro bounded and strongly Kreiss bounded (in particular, uniformly Kreiss bounded). The converses do ...

    Preconditioners based on the ISM factorization 
    Bru García, Rafael; Cerdán Soriano, Juana Mercedes; Marín Mateos-Aparicio, José; Mas Marí, José; Tuma, Miroslav (Tipografia Universitatii Ovidius, 2015)
    In this paper we survey our work on preconditioners based on the Inverse Sherman-Morrison factorization. The most important theoretical results are also summarized and some numerical conclusions are provided.

    WCG spaces and their subspaces grasped by projectional skeletons 
    Fabian, Marian; Montesinos Santalucia, Vicente (Adam Mickiewicz University, 2018-12)
    [EN] Weakly compactly generated Banach spaces and their subspaces are characterized by the presence of projectional skeletons with some additional properties. We work with real spaces. However the presented statements can ...
