On some Ringel-Hall numbers in tame cases
Let k be a finite field and consider the finite dimensional path algebra kQ, where Q is a quiver of tame type i.e. of type Ãn, D̃n,Ẽ6,Ẽ7,Ẽ8. Let H(kQ) be the corresponding Ringel-Hall algebra. We are going to determine the Ringel-Hall numbers of the form FP`XP with P, P` preprojective indecomposable...
