Families of Mutually Complementary Topologies
Several lattices of topologies on an infinite set are considered and bounds are given for the sup of the set of cardinals d such that there is a family of d mutually complementary topologies. Large classes of N<rtopologies are shown to have No-complements, and an example is given to prove that complementation is not, in general, a very selective topological operation.
متن کاملMutually complementary partial orders
Two partial orders P = (X, S) and Q = (X, s’) are complementary if P fl Q = {(x, x): x E x} and the transitive closure of P U Q is {(x. y): x, y E X}. We investigate here the size w(n) of the largest set of pairwise complementary par!iai orders on a set of size n. In particular, for large n we construct L?(n/iogrt) mutually complementary partial orders of order n, and show on the other hand tha...
متن کاملTransitive Relations, Topologies and Partial Orders
Let be a set with elements. A subset of × is a binary relation (or relation) on . The number of relations on is 22. Equivalently, there are 2 2 labeled bipartite graphs on 2 vertices, assuming the bipartition is fixed and equitable. A relation on is reflexive if for all ∈ , we have ( ) ∈ . The number of reflexive relations on is 2(−1). A relation on is antisymm...
متن کاملLinear Orders Realized by C.E. Equivalence Relations
Let E be a computably enumerable (c.e.) equivalence relation on the set ω of natural numbers. We say that the quotient set ω/E (or equivalently, the relation E) realizes a linearly ordered set L if there exists a c.e. relation E respecting E such that the induced structure (ω/E;E) is isomorphic to L. Thus, one can consider the class of all linearly ordered sets that are realized by ω/E; formall...
متن کاملFUZZY SUBGROUPS AND CERTAIN EQUIVALENCE RELATIONS
In this paper, we study an equivalence relation on the set of fuzzysubgroups of an arbitrary group G and give four equivalent conditions each ofwhich characterizes this relation. We demonstrate that with this equivalencerelation each equivalence class constitutes a lattice under the ordering of fuzzy setinclusion. Moreover, we study the behavior of these equivalence classes under theaction of a...
