BA in Computer Science, Paper II.6 16 lectures Aims The aim of this course is to introduce the student to some of the basic results and definitions of modern logic, results which go to the heart of the relationship between truth and (formal) proof. Historically, the theorems blocked the formalist approach to the foundations of mathematics begun by David Hilbert. The theorems form part of popular culture and their scope is frequently misunderstood. At the end of the course the student should be in a position to appreciate accurately the mathematical and philosophical force of the results.

Yanofsky Brooklyn College of CUNY noson@sci.brooklyn.cuny.edu Abstract. There is a common feeling that the liar's paradox, Richard's paradox, Godel's incompleteness theorem and Turing's halting problem are all very similar. They are all about limitations that occur in self-referential systems. Following F.W. Lawvere, we show that all of these logical phenomena (and many other) can be seen as instances of one simple scheme. We demonstrate this scheme and then show how this one simple scheme encompasses many different theorems in logic and theoretical computer science. No category theory is required for this talk.

UAH Math Math Club Talks Gödel's Incompleteness Theorem and the Limits of Human Knowledge Ms. Natalie Baeza Department of Mathematical Sciences University of Alabama in Huntsville December 7, 2001 For Mathematicians, the theorem means that any formal system trying to capture all mathematical truths in a finite set of axioms and rules is doomed to failure.For philosophers, it means that truth is elusive and ultimately unattainable. For all of us, Gödel’s incompleteness theorem results in the realization of the limitations of the human mind, and of the nobleness of our pursuit of knowledge. “Down how many roads among the stars must man propel himself in search of the final secret? The journey is difficult, immense, at times impossible, yet that will not deter some of us from attempting it ”

Incompleteness Theorem Kurt Gödel, pronounced somewhat like "Girdle", (April 28, 1906 - January 14, 1978) was an Austrian-born U.S. mathematician, a deep logician whose most famous work was the Incompleteness Theorem stating that any self-consistent axiomatic system powerful enough to describe integer arithmetic will allow for propositions about integers that can neither be proven nor disproven from the axioms. He also produced celebrated work on the Continuum hypothesis, showing that it cannot be disproven from the accepted set theory axioms, assuming that those axioms are consistent. Arguably, Kurt Gödel is the greatest logician of the 20th-century and one of the three greatest logicians of all time, with the other two of this historical triumvirate being Aristotle and Frege Other relative links Gödel Mathematic Proof of Gödel's Incompleteness Theorem Gödel's Theorem and Information Implications ...

75. Chapter 6. An Incompleteness Theorem For Bytecode Verifiers An incompleteness theorem for Bytecode Verifiers. The bytecode verifieris a key component of Java security. Practical bytecode verifiers http://medialab.di.unipi.it/doc/JNetSec/jns_ch6.htm

An Incompleteness Theorem for Bytecode Verifiers The bytecode verifier is a key component of Java security. Practical bytecode verifiers divide bytecode programs into three classes: those that will not cause problems when they run, those that will cause problems when they run, and those where the verifier is not certain. You can improve a bytecode verifier by reducing its area of uncertainty. Can you eliminate uncertainty completely? Can you build a complete bytecode verifier that determines whether a program is safe or not before it runs? The answer is no, you cannot. It is mathematically impossible. This short chapter shows why. To demonstrate this, we focus on one aspect of bytecode verification, stack-underflow checking. This involves determining whether a bytecode program will underflow the stack, by removing more items from it than were ever placed on it. Then we use the argument known as reductio ad absurdum. We assume that there is a complete stack-underflow checker and show that this assumption leads to a contradiction. This means that the assumption must have been false - a complete stack-underflow checker is impossible. Since a complete bytecode verifier must contain a complete stack-underflow checker, a complete bytecode verifier is impossible too. Suppose then that there is such a thing as a complete stack-underflow checker. We write a method in standard Java bytecode which takes as its argument the name of a class file and returns the value true if the specified class file does not underflow the stack, and false if it does.

77. Incompleteness Theorem Has Widespread Influence Over Many Issues Ranging From Di The Revolution of Gödel’s incompleteness theorems. Gödel’s First IncompletenessTheorem states that, “Any adequate axiomatizable theory is incomplete. http://www.cam.cornell.edu/~sharad/infinity/assignments/4c/al282-4c.htm

The Revolution of Gödel’s Incompleteness Theorems Kurt Gödel was a revolutionary logician. The results of his incompleteness theorems altered our understanding of many fields, including mathematics, metamathematics, philosophy, logic and artificial intelligence. Feats that we used to consider impossible are now shown possible. Creations that we used to think will be possible in the future that are now shown to be forever impossible. The far-reaching consequences of Gödel’s theorems have affected even our perception of the whole universe. Before Gödel’s theorems were published, it was believed that arithmetic is complete. Men were confident that there exists a finite set of axioms from which all true theorems within the system can be derived from. It all made sense intuitively and mathematicians believed they can formalize all of arithmetic. In 1910-1913, Bertrand Russell and Alfred North Whitehead published their three-volume Principia Mathematica. It was a noteworthy accomplishment that at the time was believed to have formalized all of arithmetic. It was a work from which all true mathematical theorems could be derived from. In other words, arithmetic was complete, for the time being. An inconsistent system is of no use to human society. It gives rise to every possible theorem, including the negations of every true statement. It thus breaks down under its own weight and cannot be used to model anything useful. Thus, we rely on consistent, but incomplete systems. Unfortunately, the result of Gödel’s incompleteness theorems seems to favor inconsistent systems – we can prove inconsistent systems to be inconsistent, but can never prove consistent systems to be consistent.
