Linear Logic, Monoidal Categories and Abstract Models of Differentiation and Integration

The goal of my project will be to continue to explore the theory of monoidal categories, especially using the techniques of linear logic. A model of linear logic is a monoidal category equipped with a monad (an endofunctor satisfying several naturality conditions). In previous work, we have defined the notion of differential category. These are models of linear logic with an additional operator which allows one to differentiate morphisms. To any model of linear logic, one can associate a second category, its Kleisli category. For differential categories, this category is a category of smooth maps. The corresponding logic, differential linear logic, was introduced by Ehrhard and Regnier. This then gives us a categorical and logical foundation for considering abstract theories of differentiation.
