# Do You Know About Semi-invariant Of A Quiver?

10 Questions | Total Attempts: 18  Settings  The semi-invariant of a quiver is an invariant up to a character of a group, in which such activity incites one on the ring of capacities and functions. It shapes a ring whose structure reflects portrayal-hypothetical or representation-theoretical properties of the quiver. To know more about the semi-invariant of a quiver, take this short, intelligent quiz.
