• Generalized Köthe-Toeplitz duals of c_∘ (Z,B(X,Y),λ ̄,p ̄) and c(Z,B(X,Y),λ ̄,p ̄)

Abstract

In this paper, we investigate generalized Köthe-Toeplitz duals of B(X,Y)-valued bilateral sequence spaces c_∘ (Z,B(X,Y),λ ̄,p ̄) and c(Z,B(X,Y),λ ̄,p ̄) where Z denotes the set of all integers, X and Y be Banach spaces, B(X,Y) denotes the Banach space of bounded linear operators from X into Y, p ̄=(p_k )_(-∞)^∞ denotes bilateral sequence of strictly positive real numbers and λ ̄=(λ_k )_(-∞)^∞ denotes bilateral sequence of complex numbers.
