Dear Category Theorists, I am currently studying a paper on logic and the author employs category theory in his work. However, he is using "multicategories" which is something I hear for the first time. Unfortunately my knowledge of CT isn't that deep and so if someone could suggest me papers/books that provide a definition of this term, I would be really grateful to him/her! Yours Sincerely, A.
