Let K=k be a Galois p-extension over a p-adic number field k and G 1 be the first ramification group. We show that any ideal A of K is absolutely oG-indecomposable if and only if the order jG 1 j does not divide the different D K=k :
For every natural number m, there exists a noncommutative valuation ring R with a completely prime ideal P so that there are exactly m nonisomorphic indecomposable injective right R-modules with P as associated prime ideal.
A conjecture of Kac states that the constant coefficient of the polynomial counting the number of absolutely indecomposable representations of a quiver over a finite field is equal to the multiplicity of the corresponding root in the associated KacαMoody Lie algebra. In this paper we give a combinat
