392125 Applied Logic I (S) (WiSe 2016/2017)

Contents, comment

Formale Logik ist an vielen Stellen mit Informatik verwoben: logische Schaltkreise sind Grundlage der Rechnerarchitektur. Beweise der NP-Schwierigkeit von Problemen bestehen oft in der Reduktion auf Erfüllbarkeit Boolescher Ausdrücke. Logik bietet ein Konzept von Berechenbarkeit und liefert etliche Probleme, die nicht algorithmisch entscheidbar sind. Aussagen- und Prädikatenlogik, temporale Logik und Logiken höherer Ordnung werden genutzt zum Nachweis der Korrektheit von Algorithmen.

Dieser Kurs hat zwei Teile: Im Wintersemester gibt es eine Vorlesung, die die verschiedenen Logiken (Aussagenlogik, Prädikatenlogik, Normalformen, modale Logik) sowie Unvollständigkeitssätze und Beweisbarkeit im Detail behandelt; im Sommersemester stellen die Teilnehmer in Vorträgen ausgewählte Themen vor.

Formal logic appears naturally in several places in computer science. Logic gates are the elementary building blocks of integrated circuits. Proofs of NP-hardness often use reductions to satisfiability of Boolean expressions. Logic provides a concept of computability, and a wealth of problems that cannot be solved algorithmically. Propositional and predicate logic, as well as temporal logic and higher-order logic are used in the verification and validation of computer algorithms.

This two-part course offers an introduction to these formal logics for those who are already acquainted with the basics of propositional logic and the language of predicate logic, such as found in the theoretical informatics course or the introduction to logic offered by the Philosophy and Linguistics Departments. In the winter term the course takes place as a lecture, covering propositional logic, first- and second-order logic, normal forms, modal logic, incompleteness theorems and more. In the summer term the course has the form of a seminar; the participants will give presentations of selected topics.
