Abstract: In this note we investigate extremal singly-even self-dual codes with minimal shadow. For particular parameters we prove non-existence of such codes. By a result of Rains, the length of extremal singly-even self-dual codes is bounded. We give explicit bounds in case the shadow is minimal.
Keywords: self-dual codes, singly-even codes, minimal shadow, bounds
