Project description
Bridging qualitative and quantitative type systems in programming
The study of programming languages often relies on qualitative type systems to understand programme behaviours, such as termination. However, to grasp complexity and resource consumption, quantitative type systems are used. Despite deep studies in both areas, their interaction remains poorly understood. With the support of the Marie Skłodowska-Curie Actions programme, the REGALIA project aims to address this gap by exploring whether quantitative information can be extracted from qualitatively typed programmes in a compositional manner. REGALIA aims to deepen our understanding by extending Girard’s approximation theorems and developing a translation algorithm between qualitative and quantitative systems. This will lead to new modular methods for studying programming languages, providing a quantitative interpretation of qualitative systems for both pure and effectful computation.
Objective
Qualitative type systems are a widespread technique exploited in the study of programming languages. Types allow to obtain relevant information on the behaviours of programs, such as termination of the evaluation. Quantitative type systems are used to achieve additional information on complexity and resource consumption. While these two families of type systems have been deeply studied, their interaction is still far to be properly understood. Given a program typed in a qualitative way, can we extract quantitative information from it in a compositional manner? This very natural and fundamental question has not received any appropriate answer yet. REGALIA aims to answer the question, deepening our understanding of the relationship between these two kinds of type systems. In order to do so, REGALIA will further develop the theory of resource approximation, by extending Girard's approximation theorems to proofs with cuts and by establishing a translation algorithm between qualitative systems and quantitative ones. I shall then exploit these results to define modular methods to study programming languages, alternative to Tait-Girard reducibility, that will offer quantitative interpretation of relevant qualitative systems in the context of both pure and effectful computation.
