Indecomposable objects in bounded derived category of $\mathbb C[x]/x^2$-mod
I think this may be accessible, as we can compute all ext between finitely generated modules.

OK, I see. Can we classify things over $\mathbb C[x]/x^n$ using your method?

Thank you, I have a question: $\mathbb C$ is indecomposable but not perfect in the derived category, so we can't find a projective resolution in the bounded derived category. How to rule out such possibility?

Thank you! The local story is still mysterious (the relation between local Langlands correspondence, local L function and period integrals seems not obvious), I will have a look on those papers.
