Abstract
We define a notion of concordance based on Euler characteristic, and show that it gives rise to a concordance group L of links in S3, which has the concordance group of knots as a direct summand with infinitely generated complement. We consider variants of this using oriented and unoriented surfaces as well as smooth and locally flat embeddings.
