On the dimensions of path algebras
WebIn graph theory, a quiver is a directed graph where loops and multiple arrows between two vertices are allowed, i.e. a multidigraph.They are commonly used in representation theory: a representation V of a quiver assigns a vector space V(x) to each vertex x of the quiver and a linear map V(a) to each arrow a.. In category theory, a quiver can be understood to be … Webpath algebras L(E) and L(F) are graded Morita equivalent if, and only if, the graph C∗-algebras C∗(E) and C∗(F) are equivariant Morita equivalent. Proof. Suppose that the …
