About this document
The Tropical Totally Positive Grassmannian by Edisy is a document available to read on EtoBox.
This paper introduces the totally positive part of the tropicalization of affine varieties, specifically focusing on the Grassmannian. The authors demonstrate that the tropical positive Grassmannians Trop+ Gr2,n, Trop+ Gr3,6, and Trop+ Gr3,7 correspond to known combinatorial structures, such as the Stanley-Pitman fan and associahedra of types An, D4, and E6. Additionally, they propose a conjecture regarding the positive part of the tropicalization of cluster algebras.
