Semi-invariant of a quiver
text:
In mathematics, given a quiver Q with set of vertices Q0 and set of arrows Q1, a representation of Q assigns a vector space Vi to each vertex and a linear map V(α): V(s(α)) → V(t(α)) to each arrow α, where s(α), t(α) are, respectively, the starting and the ending vertices of α. Given an element d ∈ N Q0, the set of representations of Q with dim Vi = d(i) for each i has a vector space structure. It is naturally endowed with an action of the algebraic group Πi∈Q0 GL(d(i)) by simultaneous base chan
