We propose a splitting algorithm for solving a system of composite monotone inclusions
formulated in the form of the extended set of solutions in real Hilbert spaces. The resluting
algorithm is an extension of the algorithm in 4. The weak convergence of the algorithm
proposed is proved. Applications[r]
