... (1) f is called fuzzy semi-open iff for every p ∈ Pr (L) there exists g ∈ LX with T(g) 6≤ p such that g ≤ f ≤ cl (g). (2) f is called fuzzy α-open iff for every p ∈ Pr (L) there exists g ∈ LX with T(g) 6≤ p such that g ≤ f ≤ int (cl (g)). (3) f is called fuzzy regular open iff f = int (cl (f )). (4) ...

An Introduction to Simplicial Sets
... In this section, we define simplicial sets without providing motivation, and we describe the combinatorial data necessary for specifying a simplicial set. We then try to build intuition by bringing in the geometric notion of simplices from algebraic topology. We first define the category ∆, a visual ...

Closure Operators in Semiuniform Convergence Spaces
... Note that every semiuniform convergence spaces (B, =) has an underlying Kent convergence spaces (B, qγ= ) defined as follows: qγ= = {(α, x) : α ∩ [x] ∈ γ= }, where γ= = {β ∈ F(B) : β × β ∈ =} [32] or [30]. 3. Closed Subsets of Semiuniform Spaces In this section, we characterize the (strongly) closed ...

Topology
... Topology is an important, classical part of mathematics. It deals with interesting objects (the Klein bottle, Bing’s house, manifolds, lens spaces, knots, . . . ). To study it in detail is a considerable enterprise (a huge subject with many subtle sub-disciplines and methods); here, however, we are ...
