1643. Gleb Pogudin, Thomas Scanlon, Michael Wibmer Solving difference equations in sequences: Universality and Undecidability E-mail: Submission date: 7 September 2019 Abstract: We study solutions of difference equations in the rings of
sequences and,
more generally, solutions of equations with a monoid action in the ring of
sequences indexed by the monoid. This framework includes, for example,
difference equations on grids (e.g., standard difference schemes) and
difference equations in functions on words. Mathematics Subject Classification: Keywords and phrases: |
