Well when I read the defintion of hypersurface in Wikipedia:
In algebraic geometry, a hypersurface in projective space of dimension n is an algebraic set that is purely of dimension n − 1. It is then defined by a single equation F = 0, a homogeneous polynomial in the homogeneous coordinates. (It may have singularities, so not in fact be a submanifold in the strict sense.)
Letting out the subtleties, the hypersurface of hypervolume -I must be dI= - I lnI = -pi/2
And, for hypervolume I -> dI = IlnI = pi/2.
Because there is nothing else given, the only way to reduce infinite dimensionality of hypervolume I to (infinity -1 ) is by taking a differential of it.
