... Example 17. A space in which components do not equal quasicomponents. Consider S = {0} ∪ {1/n : n ∈ N} with the topology inherited from the real line and X = ({0, 1} × {0}) ∪ (I × {1/n : n ∈ N}) ⊂ I × S. Let p = h0, 0i and q = h1, 0i. Then the component of p is {p} while the quasicomponent of p is { ...

... three non-collinear points, they are equal. We shall assume the reader is familiar with the most basic elements of set theory, as well as the fundamentals of mathematical proof. Nothing else about the reader’s mathematical background is taken for granted. As a result, Brouwer’s Fixed-Point Theorem a ...

FUZZY PSEUDOTOPOLOGICAL HYPERGROUPOIDS 1
... As the hyperoperation ”·” is a mapping from H × H to P ∗ (H) giving topologies on H and P ∗ (H) we can speak about the continuity of ”·”. Unfortunately, if a topology is given on H, there is no standard straightforward way of generating a topology on P ∗ (H). This leads to the following definition. ...
