| Summary |
The concept of interval-valued $(\alpha ,\beta )$-fuzzy ideals,
interval-valued $(\alpha ,\beta )$-fuzzy generalized bi-ideals are
introduced in LA-semigroups, using the ideas of belonging and
quasi-coincidence of an interval-valued fuzzy point with an interval-valued
fuzzy set and some related properties are investigated. We define the lower
and upper parts of interval-valued fuzzy subsets of an LA-semigroup. Regular
LA-semigroups are characterized by the properties of the lower part of
interval-valued $(\in ,\in \vee q)$-fuzzy left ideals, interval-valued $(\in
,\in \vee q)$-fuzzy quasi-ideals and interval-valued $(\in ,\in \vee q)$%
-fuzzy generalized bi-ideals. |
