In this paper, we determine the upper and lower bounds for the norm of lower triangular matrix operators on Cesà, ro weighted (p, v)−, fractional DIFFERENCE SEQUENCE SPACES of modulus functions. We consider the matrix operators acting between ℓ, p(w) and Cp(v, ω, , Δ, (η, , ℓ, ), F) and identify their bounds and vice-versa. We also investigate the same characteristics for Nö, rlund and weighted mean matrix operators.
