Abstract



The
point standing out in the present paper is the sequence spaces ,  and produced
by the domain of the infinite matrix ,
which is defined in the previous study of Candan [2], where the spaces ,  and ,
respectively, are as presented by G.G. Lorentz utilizing the issue of the
Banach limits (Acta.  Math.  80. 
1948, 167-190), andis
the double sequential band matrix and G is the generalized weighted mean.
Firstly, it is shown that aforementioned spaces are linearly isomorhic to the
spaces ,  and ,
respectively. In addition to these, andduals
of the spaces  and  are given. Beyond them, the classes  and   of infinite matrices are characterized, where
 is a given sequence space.

Abstract



Banach limiti (Acta.  Math.  80. 
1948, 167-190) kavramını kullanarak G.G. Lorentz hemen hemen
yakınsak dizilerin  uzayını tanımladı. Bu çalışmada öne çıkan
nokta ,  ve  uzaylarının 
Candan [2] tarafından tanımlanan  matris etki alanında olan ,  ve  uzaylarını tanımlamaktır. Burada ikili
dizisel band matrisi de
genelleştirilmiş ağırlıklı ortalamayı göstermektedir. Çalışmada öncelikle ,  ve uzaylarının
sırası ile ,  ve uzaylarına
lineer izomorf oldukları gösterildikten sonra  ve uzaylarının
sırası ile vedualleri
elde edilmiştir. Son bölümde de verilen
herhangi bir dizi uzayı olmak üzere  ve matris sınıflarının karekterizasyonu
verilmiştir.
