A Diagram of Galois Connections of Closure Operators
In this chapter we bring further insight into the relationship between different types of closure operators and some related classes of M-subobjects. Indeed we obtain the following commutative diagram of Galois connections whose details will be explained in the sequel: We proceed to introduce all the involved Galois connections and then we show the commutativity of the diagram.
