Software

  • The SageMath package rec_sequences provides a framework to work with sequences satisfying linear recurrence equations. It can be used to work with C^2-finite sequences and to show inequalities of C- and D-finite sequences. The package can be obtained from Github. The documentation is available here.
  • The Mathematica package PositiveSequence can be used to show inequalities of C- and D-finite sequences. It is part of the RISCErgoSum collection of packages. The source code is available on Github.
