Skew-monoidal reflection and lifting theorems

Stephen Lack and Ross Street

This paper extends the Day Reflection Theorem to skew monoidal categories. We also provide conditions under which a skew monoidal structure can be lifted to the category of Eilenberg-Moore coalgebras for a comonad.

Keywords: skew monoidal category, reflective subcategory, warping, comonad
