EU flag and COST acknowledgement
COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks. Our Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research, career and innovation.

The aim of this WG is to develop a comprehensive theory of type theories, which (i) accounts for its domain-specific variants and the type theories currently used in proof assistants, and (ii) allows for the modular reasoning about their syntax and semantics.
