The main goal of this paper is to compute norms and lower bounds for some matrix operators from the weighted sequence space. l(p)(w) into a new space called as Fibonacci weighted difference sequence space. For this purpose, we firstly introduce the Fibonacci difference matrix (F) over tilde and the space consisting of sequences whose (F) over tilde -transforms are in l(p)((w) over tilde).en10.1002/mma.5244info:eu-repo/semantics/closedAccessFibonacci numbersmatrix operatorsquasi summable matricessequence spacesArticle421651435153WOS:000503431300003Q1Q2
