A “Cuntz–Krieger uniqueness theorem” for relative Cuntz–Pimsner rings is also given and condition (L) and condition (K) for relative Cuntz–Pimsner rings are introduced. As applications of these results, a uniqueness result for the Toeplitz algebra of a directed graph and characterizations of when crossed products of a ring by a single automorphism and fractional skew monoid rings of a single corner isomorphism are simple, are obtained.}, keywords = {Cuntz–Pimsner rings}, keywords = {Simplicity}, keywords = {Invariant cycles}, keywords = {Condition (L)}, keywords = {Cuntz–Krieger uniqueness}, keywords = {Toeplitz rings}, keywords = {Leavitt path algebras}, keywords = {Crossed products}, keywords = {Fractional skew monoid rings}, title = {Simple Cuntz-Pimsner rings}, doi = {10.1016/j.jalgebra.2012.08.005}, author = {Carlsen, T.M. and Ortega, E. and Pardo Espino, Enrique}, }
