    "abstract": "A manifestly N=2 supersymmetric coset formalism is applied to analyse the\n\"fermionic\" extensions of N=2 $a=4$ and $a=-2$ KdV hierarchies. Both these\nhierarchies can be obtained from a manifest N=2 coset construction. This coset\nis defined as the quotient of some local but non-linear superalgebra by a\n$\\hat{U(1)}$ subalgebra. Three superextensions of N=2 KdV hierarchy are\nproposed, among which one seems to be entirely new.",
