We have proposed a q-analogue c ( F ( q ) ) and c 0 ( F ( q ) ) of Fibonacci sequence spaces, where F ( q ) = ( f k m q ) denotes a q-Fibonacci matrix defined in the following manner:

f k m q = { q m + 1 f m + 1 ( q ) f k + 3 ( q ) 1 , if 0 m k , 0 , if m > k ,

for all k , m Z 0 + , where ( f k ( q ) ) denotes a sequence of q-Fibonacci numbers. We developed a Schauder basis and determined several important duals ( α-, β-, γ-) of the aforesaid constructed spaces c ( F ( q ) ) and c 0 ( F ( q ) ). Additionally, we examined certain characterization results for the matrix class ( U , V ), where U { c ( F ( q ) ) , c 0 ( F ( q ) ) } and V { , c , c 0 , 1 }. Essential conditions for the compactness of the matrix operators on the space c 0 ( F ( q ) ) via the Hausdorff measure of noncompactness (Hmnc) were presented.
