This paper connects the three notions using Lack's technique for composing PRO(P)s via distributive laws. We show that Lawvere categories can be seen as the composite PROP , where expresses the algebraic structure in linear form and express the ability of copying and discarding them. In turn the PROP can be decomposed in terms of PROs as where expresses the ability of permuting variables and is the PRO encoding the syntactic structure without permutations. date: 2018-02 date_type: published publisher: ELSEVIER SCIENCE INC official_url: http://doi.org/10.1016/j.jlamp.2017.12.002 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1540501 doi: 10.1016/j.jlamp.2017.12.002 lyricists_name: Zanasi, Fabio lyricists_id: FZANA74 actors_name: Zanasi, Fabio actors_name: Turnbull, Sarah actors_id: FZANA74 actors_id: SLTUR91 actors_role: owner actors_role: impersonator full_text_status: public publication: Journal of Logical and Algebraic Methods in Programming volume: 95 pagerange: 128-146 pages: 19 issn: 2352-2208 citation: Bonchi, F; Sobocinski, P; Zanasi, F; (2018) Deconstructing Lawvere with distributive laws.
