The rest is - currently worked on by Antoine Hersen. See also WorkshopRisc2006. + Update: Some of these are meanwhile implemented in [GuessingFormulasForSequences]. A zero test for algebraic differential equations is described by Joris van der Hoeven. ??changed: Update: To get things started, I implemented an operator that represents recurrences. - Look at RecurrenceRelationOperator. This will be integrated into Antoine Hersen's - hierarchy. + Look at RecurrenceRelationOperator. This should be integrated into a proper hierarchy including rational functions, algebraic functions, holonomic functions and differentially algebraic functions, on one hand, linear recurrences with constant coefficients, linear recurrences with polynomial coefficients, "ordinary" recurrences on the other hand. -- forwarded from http://wiki.axiom-developer.org/[EMAIL PROTECTED]
