Course Objective

The course objective is to obtain a good knowledge and understanding of
the most important logical systems: propositional logic, predicate
logic, and modal logic. (Knowledge and understanding)

The students learn to use these systems to model data, knowledge, and
actions. (Applying knowledge and understanding)

An important aspect of the course is the ability to reason using these
logics and reason about these logics: what can and what can not be
expressed with a logic system, and what are the differences between the
systems with respect to expressive power or the existence of decision
procedures. (Applying knowledge and understanding) (Making judgements)

Course Content

The focus of the lecture is on propositional logic and first-order
predicate logic. We work with natural deduction as a proof system. The
relation between semantic and syntactic methods is important; the
central keywords are correctness, consistency, and completeness.
Moreover, we pay attention to expressive power, for example when
formulating queries. A fundamental tool, for this purpose, is the
compactness theorem.

Algorithmically there is the contrast between the decidability of
propositional logic and the undecidability of predicate logic (for
example, seen by a coding of the Post Correspondence Problem).
As a variation of the mentioned logics, we consider modal logic with
Kripke models as semantics.
