“…Problem SEP is an extension of many mathematical models which have been considered and studied intensively by several authors recently: split variational inequality problems [12], split common fixed point problems [7,13,16,19,28,31,36,[38][39][40], and the split feasibility problems which have been used for studying medical image reconstruction, sensor networks, intensity modulated radiation therapy, and data compression; see [5,[8][9][10] and the references quoted therein.…”
