In this paper,we establish a connection between cluster algebras and a class of modules of the quantum affine algebra ??? of type G2,which is called prime snake mod-ules.Firstly,we give the definition for prime snake modules of type G2,and find the mutation sequences for the prime snake modules.Secondly,we find a system of equations for the prime snake modules.Finally,we show that the equations in the system of type G2 correspond to mutations in some cluster algebra ???,moreover,every prime module in these equations corresponds to a cluster variable in some cluster algebra ???. |
