Research focus
Our aim is to develop and apply non-classical logics for reasoning, in both natural and artificial scenarios, with real-life information, which is often uncertain, graded, or even contradictory and changing in time.
More specifically, we focus on the study of (abstract) algebraic logic, mathematical fuzzy logic, substructural, relevant, modal and paraconsistent logics, developing dynamic and non-monotonic frameworks, and studying complexity problems of these logics.
Current research projects
- Non-classical Logical Models of Information Dynamics. Czech Science Foundation, 2018-2020.
- The project aims at developing and studying dynamic logics based on non-classical logic.
- Reasoning with Graded Properties. Czech Science Foundation, 2018-2020.
- Joint project with Institute of Information Theory and Automation of the Czech Academy of Sciences with the goal to develop a logic-based theory of reasoning with graded properties: to provide a conceptual study of the different kinds of such properties, new solutions to sorites paradoxes, comparison with linguistic graded theories, and a framework for counterfactual and defeasible reasoning.
Past research projects are listed here.
