Resumen:
We investigate the behavior of finitely generated projective modules over a down-up algebra. Specifically, we show that every noetherian down-up algebra A(a,b,c) has a non-free, stably free right ideal. Further, we compute the stable rank of these algebras using Stafford´s Stable Range Theorem and Kmax-dimension. https://doi.org/10.1016/j.jalgebra.2018.02.037
