RT Journal Article T1 Representation Theorems for Some Operator Ideals A1 Cobos Díaz, Fernando A1 Resina, Ivam AB We establish representation theorems in terms of finite rank operators for some operator ideals defined by approximation numbers. We also study the stability under tensor product of these ideals.
