Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous.In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic – do not vary smoothly in this way, but have distinct, separated values. A relation is any association or link between elements of one set, called the domain or (less formally) the set of inputs, and another set, called the range or set of outputs. endstream endobj 82 0 obj <> endobj 83 0 obj <> endobj 84 0 obj <>stream A relation R on set A is called Reflexive if ∀a∈A is related to a (aRa holds).
