It would be interesting to know if there exist nontrivial examples of topological equivalence for dgas defined over a field. Here is one negative result along these lines, whose proof is given in Section 5.7. Proposition 1.7.

Webuses the relation-based model (Chapter 4) as a basis to develop a computational tool to assess topological equivalence between two spatial scenes. Topological equivalence is analyzed in terms of individual representations for spatial objects, as well as considering spatial scenes composed of a collection of these individual object representations. WebLet X be a topological space and let ∼ be an equivalence relation on X. Denote by X / ∼ the set of equivalence classes, also known as quotient, and let π: X → X / ∼, x ↦ [x] denote the corresponding quotient projection. Here [x] = {y ∈ X: x …

WebBy using three equivalence relations, we characterize the behaviour of the elements in a hypercompositional structure. With respect to a hyperoperation, some elements play specific roles: their hypercomposition with all the elements of the carrier set gives the same result; they belong to the same hypercomposition of elements; or they have both properties, … WebTopological equivalence. The two metrics and are said to be topologically equivalent if they generate the same topology on .The adverb topologically is often dropped. There are multiple ways of expressing this condition: a subset is -open if and only if it is -open;; the open balls "nest": for any point and any radius >, there exist radii ′, ″ > such that
