ICS 241: Discrete Mathematics II (Spring 2015) 9.1 Relations and Their Properties Binary Relation Deﬁnition: Let A, B be any sets. Relations 1.1. Product Sets Definition: An ordered pair , is a listing of the objects/items and in a prescribed order: is the first and is the second. Partial Orderings Let R be a binary relation on a set A. R is antisymmetric if for all x,y A, if xRy and yRx, then x=y. We denote this by aRb. For the most part, we will be interested in relations where B= A. 3.2 Operations on Binary Relations 163 3.2.1 Inverses 163 3.2.2 Composition 165 3.3 Exercises 166 3.4 Special Types of Relations 167 3.4.1 Reflexive and Irreflexive Relations 168 3.4.2 Symmetric and Antisymmetric Relations 169 3.4.3 Transitive Relations 172 … The equivalence classes are called the strong components of G. G is strongly connected if it has just one strong component. Each directed edge (u ; v ) 2 E has a start (tail ) vertex u , and a end (head ) vertex v . R is transitive x R y and y R z implies x R z, for all x,y,z∈A Example: i<7 … math or computer science. 2 CS 441 Discrete mathematics for CS M. Hauskrecht Binary relation Definition: Let A and B be two sets. discrete math relations and digraphs To draw the.Graphs and Digraphs Examples. For example, the individuals in a crowd can be compared by height, by age, or through any number of other criteria. The course exercises are meant for the students of the course of Discrete Mathematics and Logic at the Free University of Bozen-Bolzano. (8a 2Z)(a a (mod n)). Combining Relation: Suppose R is a relation from set A to B and S is a relation from set B to C, the combination of both the relations is the relation which consists of ordered pairs (a,c) where a Є A and c Є C and there exist an element b Є B for which (a,b) Є R and (b,c) Є S. R is a partial order relation if R is reflexive, antisymmetric and transitive. y> is a member of R1 and
