Relations and Functions . Sets are usually described using "fg" and inside these curly brackets a list of the elements or a description of the elements of the set. Set Theory 5. The structure of this proof makes a very convincing demonstration of the validity of the rule of Hypothetical Syllogism. 2 Sets A set is a collection of objects, which are called elements or members of the set. The following book is nearly 600 pages long and proceeds at a very slow pace. Some early catastrophies, such as the discovery of Logic andSet Theory Lectured by I.B.Leader, LentTerm 2005, 2010 Chapter 1 Propositional Logic 1 Chapter 2 Well-Orderings and Ordinals 7 Chapter 3 Posets and Zorn’s Lemma 16 Chapter 4 Predicate Logic 24 Chapter 5 Set Theory 34 Chapter 6 Cardinals 43 Bonus lecture Incompleteness Examples Sheets Prerequisites. 4 CS 441 Discrete mathematics for CS M. Hauskrecht Equality Definition: Two sets are equal if and only if they have the same elements. set theory is a theory of pure well-founded sets and its intended models are structures of the form hR( );2i, where the numbers will depend upon the particular axioms included in the theory. . WUCT121 Logic Tutorial Exercises Solutions 2 Section 1: Logic Question1 … Is the This serves to establish that p was not true to begin with. At £41, it is not cheap.

Logic appears in a ‘sacred’ and in a ‘profane’ form; the sacred form is domi-nant in proof theory, the profane form in model theory. +(2n-1) = n 2 Ó Assume ÒInductive HypothesisÓ: Sk (foranyparticular k ' 1) 1+3+5+É+ (2k-1) = k2 Add (2k+1) to both sides. Jon Barwise and John Etchemendy, Language Proof and Logic, 2nd edition (University of Chicago Press, 2003) The notes would never have reached the standard of a book without the Proof is, how-ever, the central tool of mathematics. proof. A special case of Conditional Proof is to assume p and then reach as a contradiction the conjunction of q and ~ q for some sentence q. Common Sets. Proofs 4. Here are some important sets: The phenomenon is not unfamiliar, one observes this dichotomy also in other areas, e.g. 1+3+5+É+ (2k-1)+(2k+1) = k2 +(2k+1) Sum of first k+1 odd numbers= (k+1)2 CONCLUDE: Sk+1 Sn & ÒThe sum of the first n odd numbers is n 2.Ó Indirect Proof. WUCT121 Logic Tutorial Exercises Solutions 1 WUCT121 Discrete Mathematics Logic Tutorial Exercises Solutions 1. Set theory is also the most “philosophical” of all disciplines in mathematics. The big questions cannot be dodged, and students will not brook a flippant or easy answer. The order of the elements in a set doesn't contribute The objects in a set will be called elements of the set. set the-ory and recursion theory. Sn & ÒThe sum of the first n odd numbers is n2.Ó Equivalently, Sn is the statement that: Ò1 + 3 + 5 + (2k-1) + . purposes, a set is a collection of objects or symbols. Some book in proof theory, such as [Gir], may be useful afterwards to complete the information on those points which are lacking. Predicate Logic 3. Dirk van Dalen, Logic and Structure (Springer, 1994). Example: • {1,2,3} = {3,1,2} = {1,2,1,3,2} Note: Duplicates don't contribute anythi ng new to a set, so remove them. Questions are bound to come up in any set theory course that cannot be answered “mathematically”, for example with a formal proof. In standard introductory classes in algebra, trigonometry, and calculus there is currently very lit-tle emphasis on the discipline of proof. This text is for a course that is a students formal introduction to tools and methods of proof. A )(B )C) (A and B) )C conditional proof In a course that discusses mathematical logic, one uses truth tables to prove the above tautologies. Logic 2. Two sets are equal when they have the same elements.
