In the case of real root representations of small defect, the non-empty cells are in one-to-one correspondence to certain, so called non-contradictory, subsets of the vertex set of a fixed tree-shaped coefficient quiver. In the second part, we use this characterization to determine the generating functions of the Euler characteristics of the quiver Grassmannians (resp. F-polynomials). 2023-04-03T09:20:00Z 2023-04-03T09:20:00Z 2021 Book https://link.springer.com/article/10.1007/s10468-021-10097-z https://dlib.phenikaa-uni.edu.vn/handle/PNK/7455 en application/pdf Springer
