This is generally the Cartesian product of the underlying sets (or some subset of it), together with a suitably defined structure. More abstractly, the direct sum is often, but not always, the coproduct in the in question. In cases where an object is expressed as a direct sum of subobjects, the direct sum can be referred to as an internal direct sum. |
