Yes, they are relevant but not central to the issue that you raised. In fact the concept of "indefinities" was coined by Tim Daly. After reading about the idea, I do not think that this formulation of the issue (which is essentially based on proof theory and logic) is the right approach for Axiom. Really I would prefer a more "algebraic" approach. I think the paper by Steven Watt referred to in the following thread: http://lists.nongnu.org/archive/html/axiom-developer/2006-08/msg00525.html Making Computer Algebra More Symbolic (Invited), Stephen M. Watt, pp. 43-49, Proc. Transgressive Computing 2006: A conference in honor or Jean Della Dora , (TC 2006), April 24-26 2006, Granada Spain. http://www.csd.uwo.ca/~watt/pub/reprints/2006-tc-sympoly.pdf is a very important contribution. What he is describing here is directly related to the implementation of the Expression domain constructor in Axiom.
