# Generic logical semantics of justifications.

## Sergei Artemov

### The CUNY Graduate Center

Proofs and justification are gradually making their way from meta-logical notions into the formal logic itself and becoming mathematical logical objects. This makes the logic language (much) more precise and connects the logic apparatus to numerous new areas of interest. In this talk, we describe a generic logical semantics of justifications within the classical truth values logic framework: justifications here appear as sets of formulas with appropriate closure conditions.

Professor Artemov holds a Distinguished Professor position at the Graduate Center of the City University of New York, in the Computer Science, Mathematics and Philosophy programs. He is also Professor of Mathematics at Moscow State University, the founder and the Head of the research laboratory Logical Problems in Computer Science. He conducts research in the areas of logic in computer science, mathematical logic and proof theory, knowledge representation and artificial intelligence, automated deduction and verification and optimal control and hybrid systems.
