We have proposed a -analogue and of Fibonacci sequence spaces, where denotes a -Fibonacci matrix defined in the following manner:
for all , where denotes a sequence of -Fibonacci numbers. We developed a Schauder basis and determined several important duals (-, -, -) of the aforesaid constructed spaces and . Additionally, we examined certain characterization results for the matrix class , where and . Essential conditions for the compactness of the matrix operators on the space via the Hausdorff measure of noncompactness (Hmnc) were presented.
