Indecomposable invariants of quivers for dimension (2,...,2) and maximal paths
arXiv:0704.2411
Abstract
An upper bound on degrees of elements of a minimal generating system for invariants of quivers of dimension (2,...,2) is established over a field of arbitrary characteristic and its precision is estimated. The proof is based on the reduction to the problem of description of maximal paths satisfying certain condition.
