The articles [3], [1], and [2] provide the notation and terminology for this paper. The arguments of the notions defined below are the following: f which is an object of the type Function; a, b which are objects of the type Any. The functor f .(a, b), with values of the type Any, is defined by it = f .a, b. One can prove the following proposition (1) for f being Function for a,b being Any holds f .(a, b) = f .a, b. In the sequel A, B, C will denote objects of the type DOMAIN. The arguments of the notions defined below are the following: A, B, C which are objects of the type reserved above; f which is an object of the type Function of [:A, B:], C; a which is an object of the type Element of A; b which is an object of the type Element of B. Let us note that it makes sense to consider the following functor on a restricted area. Then f .(a, b) is Element of C.","PeriodicalId":348406,"journal":{"name":"Introductory Concepts for Abstract Mathematics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130704272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For these notes we'll look at one set U , called the universal set, and its subsets. In later notes, we'll build new sets out of old ones using the product construction and the powerset construction. The universal set U corresponds to the domain of discourse in predicate logic when we're only considering unary predicates on that domain. Let, for instance, U be the set of integers, usually denoted Z. A couple of unary predicates for this domain are S(x): x is a perfect square,\" and P (x): x is a positive integer.\" These two predicates correspond to two subsets of U . The rst corresponds to the set of perfect squares which includes 0; 1; 4; 9; etc., and the second corresponds to the set of positive integers which includes 1; 2; 3; etc. The subset that corresponds to a unary predicate is called the extent of the predicate. There's such a close correspondence between a unary predicate and it's extent that we might as well use the same symbol for both. So, we can use S for the subset of perfect squares, or S for the predicate which indicates with the notation S(x) whether an integer x is a perfect square or not. There are a couple of ways to use notation to specify a set. One is by listing its elements, at least the rst few, and hoping the reader can understand your intent.","PeriodicalId":348406,"journal":{"name":"Introductory Concepts for Abstract Mathematics","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114208717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
