Covariant derivative in shape space in terms of preshape<br />
(O’Neill1966):<br />
∇ ∗ X ∗<br />
Y ∗ = H∇ X Y<br />
Vertical directi<strong>on</strong> is JN, where N is outward unit normal at the<br />
preshape, J is almost complex structure <strong>on</strong> C N .<br />
So parallel transport in small steps in upstairs space then do<br />
