Are there some references about tropical cluster algebras and tropical Laurent phenomenon? I searched on Google but only found one paper: Tropical Plucker functions and their bases .

Thank you very much.

Let me suggest Lauren Williams and my paper as a starting point:

David Speyer and Lauren Williams, MR 2164397 The tropical totally positive Grassmannian, J. Algebraic Combin. 22 (2005), no. 2, 189--210.

It's earlier than a lot of the other references mentioned, so it isn't as sophisticated but, for that reason, it is a lot more concrete.

There are certainly things related to tropical cluster algebras associated to surfaces. See Fomin, Shapiro, Thurston, https://arxiv.org/pdf/math/0608367, especially section 9.5, and the sequel by Fomin and Thurston, https://arxiv.org/abs/1210.5569, sections 14 and 15.

There is also work by Fock and Goncharov along similar lines, see for example https://arxiv.org/abs/math/0510312. (Note that this is much more accessible than some of their work!)

  • $\begingroup$ thank you very much for the references. It seems that they didn't mention the tropical Laurent phenomenon in these papers? $\endgroup$ – Jianrong Li Jan 11 '17 at 15:07
  • $\begingroup$ I can believe that. $\endgroup$ – Hugh Thomas Jan 11 '17 at 15:12
