We have seen that the language of propositional logic allows us to build up expressions from propositional variables A, B, C, \ldots using propositional connectives like \to, \wedge, \vee, and \neg.

In this chapter, you will learn how to write proofs in Lean. We will start with a purely mechanical translation that will enable you to represent any natural deduction proof in Lean. We will see, ...

Define the following logic terms and apply them to real-world problems: Describe the simple model checking algorithm and the theorem proving algorithms - forward chaining and resolution, what they ...

We attempt to define the classical propositional logic by use of appropriate derivability conditions called Cn-definitions. The conditions characterize basic properties of propositional connectives.

Abstract: Based on the analysis of the constructions of T-conclusion by means of deduction theorems, completeness theorems and the theory of truth degree of formulas, the present papers introduces the ...

when thinking about logical agents, we imagine that the agent has a knowledge base (KB for short) that contains logical sentences that describe the state of the world you could think of a KB as a ...
