Abstract

By means of the residual implication on a frame L , a degree approach to L -continuity and L -closedness for mappings between L -cotopological spaces are defined and their properties are investigated systematically. In addition, in the situation of L -topological spaces, degrees of L -continuity and of L -openness for mappings are proposed and their connections are studied. Moreover, if L is a frame with an order-reversing involution ′ , where b ′ = b → ⊥ for b ∈ L , then degrees of L -continuity for mappings between L -cotopological spaces and degrees of L -continuity for mappings between L -topological spaces are equivalent.
