To calculate the optimality conditions of the following problem [mathematical expression not reproducible], where C ([[OMEGA].sub.0]) is the set of admissible forms obtained by diffeomorphism
, the cost function J([OMEGA]) is the compliance defined by
An optimized framework with nonrigid registration and the diffeomorphism
strategy was used, a similarity energy function based on grey value was designed, and termination conditions were set to stop iterations adaptively.
Further, we assume that there exists a diffeomorphism
h from [K.sub.1] to [K.sub.2] = h([K.sub.1]), defined by
And this turns out to be true, since black hole entropy can be shown to be the Noether charge of the diffeomorphism
Then there is a diffeomorphism
h : [[summation].sub.s] [right arrow] M, having the form h(0, y) = (a(y),y), where [alpha]'(u) > 0 at u = a(y), that maps the flow of the sliding vector field [Z.sub.s] to the flow of the reduced problem on M.
It is clear that det D[phi](u, v, [tau]) = (1/q)(a + [K.sup.2][u.sup.2]) > 0, and [phi] is a diffeomorphism
The main moduli spaces in which we are interested are moduli spaces of manifolds, Or equivalently classifying spaces of diffeomorphism
groups of manifolds.
A solution to the Ricci flow is called Ricci soliton if it moves only by a one parameter group of diffeomorphism
Technically, the Smale's construction involves a planar diffeomorphism
, acting on a square, whose image has the shape of a horseshoe that crosses the square in a suitable manner (see [43, 54, 55] for the mathematical details).

If the map is a diffeomorphism
on R, the sets [W.sup.s]([bar.x]) and [W.sup.u]([bar.x]) are the stable and unstable manifolds of [bar.x].
If [rho] < n, then a diffeomorphism
restricted to a neighborhood N can be built as
