Caldas, M.; Jafari, S.; Kovár, M. M. Some properties of \(\theta\)-open sets. (English) Zbl 1099.54501 Divulg. Mat. 12, No. 2, 161-169 (2004). Summary: We introduce and study topological properties of \(\theta\)-derived, \(\theta\)-border, \(\theta\)-frontier and \(\theta\)-exterior of a set using the concept of \(\theta\)-open sets and study also other properties of the well-known notions of \(\theta\)-closure and \(\theta\)-interior.
