“…For the soft set theory, Ali et al [2] proposed new operations on soft sets, and in [4], the new operations were investigated with the notions defined in [2,14]. Recently, the properties and applications on the soft set theory have been studied widely and applied in the various branches of mathematics [1,3,4,5,6,7,8,10,11,15,16,17,20]. In particular, the combining the soft set theory and any other notions of mathematics have been studied steadily.…”
