Abstract
A manifestly N = 2 supersymmetric coset formalism is applied to analyz e the ''fermionic'' extensions of N = 2, a = 4 and a = -2 KdV hierarch ies. Both hierarchies can be obtained from a manifest N = 2 coset cons truction. This coset is defined as the quotient of some local but nonl inear superalgebra by a (U) over cap(1) subalgebra. Three superextensi ons of N = 2 KdV hierarchy are proposed, among which one seems to be e ntirely new.
