Abstract
For a small, integral and meet-continuous quantaloid , we establish two types of Galois correspondences by considering a limit structure on a set as a
-multiple limit structure on a
-typed set. One Galois correspondence shows that the stratified
-topologies and the
-multiple limit structures based on
-typed sets can be converted to each other categorically. Moreover, the other one shows that a new mathematical structure on a
-typed set, namely ⊤-
-limit structure, can be obtained from
-multiple limit structures categorically. In the case that
is the quantaloid
(L) of diagonals obtained from a GL-quantale L, the first Galois correspondence captures a pair of concrete functors between the concrete category of
(L)-multiple limit spaces and that of stratified
(L)-topological spaces over the slice category Set↓L, and the second Galois correspondence captures a pair of concrete functors between the concrete category of
(L)-multiple limit spaces and that of ⊤-
(L)-limit spaces over the slice category Set↓L. Last but not the least, the first Galois correspondence reduces to the famous Lowen’s functors, while the second Galois correspondence captures a new relationship between the construct of limit spaces and that of ⊤-limit spaces in the case that the underlying quantale L is considered as a one-object quantaloid.
