This is basically a course on Propositional Logic. Perhaps such a course is obviously useful to Computation students but it is also useful for Mathematics students to learn about logic. Mathematical proofs are excercises in logic, but complicated by the mathematics!

## Notes on logic and set theory

Like logic, the subject of sets is rich and interesting for its own sake. We will need only a few facts about sets and techniques for dealing with them, which we set out in this section and the next. We will return to sets as an object of study in chapters 4 and 5. A set is a collection of objects; any one of the objects in a set is called a member or an element of the set. Some sets occur so frequently that there are standard names and symbols for them. There is a natural relationship between sets and logic. Example 1.

Set theory , branch of mathematics that deals with the properties of well-defined collections of objects, which may or may not be of a mathematical nature, such as numbers or functions. The theory is less valuable in direct application to ordinary experience than as a basis for precise and adaptable terminology for the definition of complex and sophisticated mathematical concepts. Between the years and , the German mathematician and logician Georg Cantor created a theory of abstract sets of entities and made it into a mathematical discipline. This theory grew out of his investigations of some concrete problems regarding certain types of infinite sets of real numbers. A set, wrote Cantor, is a collection of definite, distinguishable objects of perception or thought conceived as a whole. The objects are called elements or members of the set. The theory had the revolutionary aspect of treating infinite sets as mathematical objects that are on an equal footing with those that can be constructed in a finite number of steps.

## Logic, Set Theory and Matrices

Set theory is a branch of mathematical logic that studies sets , which informally are collections of objects. Although any type of object can be collected into a set, set theory is applied most often to objects that are relevant to mathematics. The language of set theory can be used to define nearly all mathematical objects. The modern study of set theory was initiated by Georg Cantor and Richard Dedekind in the s. After the discovery of paradoxes in naive set theory , such as Russell's paradox , numerous axiom systems were proposed in the early twentieth century, of which the Zermelo—Fraenkel axioms , with or without the axiom of choice , are the best-known. Set theory is commonly employed as a foundational system for mathematics , particularly in the form of Zermelo—Fraenkel set theory with the axiom of choice.
