Use of Some Topological Concepts in the Study of Some COVID−19 Symptoms

Samirah ALZahrani


We apply some topological concepts on topological spaces generated from both equality and similarity relation for our information system, which examine 10 hypothetical patients who suffer from some COVID−19 symptoms. This is based on the degree of accuracy generated from the cardinality of the lower and upper approximation. This method is clarified by application.


Rough sets, topology, similarity, lower and upper approximation, accuracy
