1-loop quiver and the classification of quivers Gabriel's theorem states that finite type quivers are exactly the ones whose underlying graphs are ADE type Dynkin diagrams. Furthermore, the quivers whose underlying di...
Similarly this is true for the $\tilde{A}_n$-quiver with cyclic orientation. When one says that a quiver is tame one usually restricts to the case of acyclic quivers.

How to show that the ordinary quiver of a semisimple algebra is a quiver consisting of isolated points? It is said that the ordinary quiver of a semisimple algebra is a quiver consisting of isolated points? How to pro...
According to that definition, the arrows between points correspond to elements in the basis of $e_a(rad(A)/rad(A)^2)e_b$. In a semisimple ring, $rad(A)=\\{0\\}$, so such a basis would be empty. So there are no arrows between distinct points.

Quiver Plot in Matplotlib - GeeksforGeeks
Feb 23, 2022Quiver Plot with two arrows. Let's add another arrow to the plot passing through two starting points and two directions. By keeping the original arrow starting at origin(0, 0) and pointing towards up and to the right direction(1, 1), and create the second arrow starting at (0, 0) pointing down in direction(0, -1).To see the starting and ending point clearly, we will set axis limits to [-1.5 ...

Quiver Algebras of Coverings and Twisted Tensor Products
Given a covering Γ of a quiver Δ, we show that the quiver algebra K[Γ] of Γ over a field K is a twisted tensor product of the quiver algebra of the fibre of the covering viewed as a trivial quiver and the quiver algebra K[Δ]. To make sense of this, we first extend the theory of twisted tensor products of algebras to include algebras without units.

You can check that for arrow $j\to i$ in the Ext-quiver, the corresponding map $P_i\to P_j$ (resp. $I_j\to I_i$) is irreducible. $Q$), where $Q$ is the Ext-quiver of $A$.
