We show that any matrix in the semigroup is a product of matrices in M whose length is at most 2^{n (2 n + 3)} g(n)^{n+1} ∈ 2^{O(n² log n)}, where g(n) is the maximum order of finite groups over rational n × n-matrices. This result implies algorithms with an elementary running time for deciding finiteness of weighted automata over the rationals and for deciding reachability in affine integer vector addition systems with states with the finite monoid property. date: 2020-06-29 date_type: published publisher: Schloss Dagstuhl--Leibniz-Zentrum official_url: https://doi.org/10.4230/LIPIcs.ICALP.2020.115 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1780281 doi: 10.4230/LIPIcs.ICALP.2020.115 lyricists_name: Haase, Christoph lyricists_id: CHAAS66 actors_name: Haase, Christoph actors_id: CHAAS66 actors_role: owner full_text_status: public series: Leibniz International Proceedings in Informatics (LIPIcs) place_of_pub: Dagstuhl, Germany pagerange: 115 event_title: 47th International Colloquium on Automata, Languages and Programming (ICALP 2020) institution: 47th International Colloquium on Automata, Languages and Programming (ICALP 2020) issn: 978-3-95977-138-2 book_title: Proceedings of the 47th International Colloquium on Automata, Languages, and Programming (ICALP 2020) citation: Bumpus, G; Haase, C; Kiefer, S; Stoienescu, P-I; Tanner, J; (2020) On the Size of Finite Rational Matrix Semigroups.
