Banach lattices of L-weakly and M-weakly compact operators
Bayram, Erdal; Wickstead, A. W. (Springer Basel Ag, 2017)We give conditions for the linear span of the positive L-weakly compact (resp. M-weakly compact) operators to be a Banach lattice under the regular norm, for that Banach lattice to have an order continuous norm, to be an ... -
Invariant subspaces of operators quasi-similar to L-weakly and M-weakly compact operators
Bayram, Erdal (Scientific Technical Research Council Turkey-Tubitak, 2018)Let T be an L-weakly compact operator defined on a Banach lattice E without order continuous norm. We prove that the bounded operator S defined on a Banach space X has a nontrivial closed invariant subspace if there exists ... -
L- ve M-zayıf Kompakt Operatörlerin Sıra Yapısı Üzerine
Bayram, Erdal (2018)Banach örgüleri üzerinde tanımlı zayıf kompakt operatörlerin alt sınıfları olan L-zayıf ve M-zayıf kompaktoperatörlerin genelde vektör örgüsü olmadıkları bilinmesine rağmen sıra yapılarına dair çalışmalar literatürdegörü ... -
L-weakly and M-weakly compact operators and the centre
Bayram, Erdal; Wickstead, A. W. (Springer Basel Ag, 2017)We extend known results concerning the centre of spaces of regular (resp. weakly compact or compact) operators between two Banach lattices to the setting of L-weakly compact and M-weakly compact operators. We also show ... -
On the invariant supspace problem
Tonyalı, Cevriye; Bayram, Erdal (2013)In this study, we present invariant subspaces (subideals) for a class of operators (positive operators) related to M-weakly and L-weakly compact operators. Principally, these invariant subspaces can be conceivable for all ... -
On the Matrix Representations of Operators on the Classical Sequence Spaces
Bayram, Erdal (2019)The present study provides the necessary and sufficient conditions for the matrix characterizations of ??- and ??-weakly compact operators which are defined on certain classical sequence spaces as Banach lattices. It is ... -
Some compactness properties of L-weakly and M-weakly compact operators
Bayram, Erdal; Tonyali, C. (Springer, 2012)We present some compactness properties of L-weakly and M-weakly compact operators on a Banach lattice under additional conditions. Thus, we can say that every bounded operator which commutes with any L-weakly or M-weakly ... -
Sıralı uzaylarda fremlin tensör çarpımları
Tonka, Yağmur Nur (Tekirdağ Namık Kemal Üniversitesi, 2020)Bu çalışma matematiğin birçok branşında kullanılan tensör çarpımlarının incelenmesi üzerinedir. Esas olarak sıralı uzaylar teorisinde Arşimedyan Riesz uzaylarının ve Banach örgülerinin Fremlin tensör çarpımlarının sistematik ...
