Bases for upper cluster algebras and tropical points
نویسندگان
چکیده
It is known that many (upper) cluster algebras possess different kinds of good bases which contain the monomials and are parametrized by tropical points Poisson varieties. For a large class upper (injective-reachable ones with full rank coefficients), we describe all its these properties. Moreover, show existence generic basis for them. In addition, prove Bridgeland's representation theoretic formula effective their theta functions (weak genteelness). Our results apply to (almost) well-known arising from theory or higher Teichm\"uller theory, including quantum affine algebras, unipotent cells, double Bruhat skein over surfaces, where change coefficients if necessary so assumption holds.

These are notes from introductory survey lectures given at the Institute for Studies in Theoretical Physics and Mathematics (IPM), Teheran, in 2008 and 2010. We present the definition and the fundamental properties of Fomin-Zelevinsky’s cluster algebras.

متن کاملBases for Cluster Algebras from Surfaces
We construct two bases for each cluster algebra coming from a triangulated surface without punctures. We work in the context of a coefficient system coming from a full-rank exchange matrix, for example, principal coefficients.
متن کاملTriangular Bases in Quantum Cluster Algebras
A lot of recent activity has been directed toward various constructions of “natural” bases in cluster algebras. We develop a new approach to this problem which is close in spirit to Lusztig’s construction of a canonical basis, and the pioneering construction of the Kazhdan–Lusztig basis in a Hecke algebra. The key ingredient of our approach is a new version of Lusztig’s Lemma that we apply to a...

We construct quantized versions of generic bases in quantum cluster algebras of finite and affine types. Under the specialization of q and coefficients to 1, these bases are generic bases of finite and affine cluster algebras.
