Quantum cluster algebras from unpunctured triangulated surfaces: arbitrary coefficients and quantization
arXiv:1807.06910 · doi:10.1007/s00029-021-00750-2
Abstract
We study quantum cluster algebras from unpunctured surfaces with arbitrary coefficients and quantization. We first give a new proof of the Laurent expansion formulas for commutative cluster algebras from unpunctured surfaces, we then give the quantum Laurent expansion formulas for the quantum cluster algebras. Particularly, this gives a combinatorial proof of the positivity for such class of quantum cluster algebras.
