Muhammad İrfan Ali, Tahir Mahmood, Azmat Hussain · Journal of Taibah University for Science · 2018
Concept of generalized rough approximations for fuzzy filters in ordered semigroups is introduced. Then this idea is extended to rough approximations of fuzzy bi-filters and fuzzy quasi-filters in ordered semigroups. -fuzzy filters are a generalization of fuzzy filters and these can be further generalized by -fuzzy filters. Generalized roughness has been studied for both and -fuzzy filters of ordered semigroups.
