We show that, except in one particular case, mutation-cyclic matrices give rise to … Webgraded cluster algebras are particularly important when studying cluster algebra structures on the (multi-)homogeneous coordinate rings of projective varieties, as one naturally expects. Another important generalisation concerns the quantization of cluster algebras, that is, a noncommutative version of the theory.

Quantum cluster algebras and their specializations

WebWe then study gradings for finite type cluster algebras without coefficients, giving a full classification. Translating the definition suitably again, we obtain a notion of multi-grading for (generalised) cluster categories. This setting allows us to prove additional properties of graded cluster algebras in a wider range of cases. http://arxiv-export3.library.cornell.edu/pdf/1510.04109v1 inchinnan care home address
