Some new Fibonacci difference spaces of non-absolute type and compact operators

Abstract

The aim of the paper is to introduced the spaces $c_0^{\lambda }(\hat{F})$ and $c^{\lambda }(\hat{F})$ which are the BK-spaces of non-absolute type and also derive some inclusion relations. Further, we determine the $\alpha -,\beta -,\gamma -$duals of those spaces and also construct their bases. We also characterize some matrix classes on the spaces $c_0^{\lambda }(\hat{F})$ and $c^{\lambda }(\hat{F}).$ Here we characterize the subclasses $\mathcal{K}(X,Y)$ of compact operators where $X$ is $c_0^{\lambda }(\hat{F})$ or $c^{\lambda }(\hat{F})$ and $Y$ is one of the spaces $c_0,c,l_{\infty },l_1,bv$ by applying Hausdorff measure of noncompactness.
