Derivative of 2 norm
WebFor the second point, this derivative is sometimes called the "Fréchet derivative" (also sometimes known by "Jacobian matrix" which is the matrix form of the linear operator). It is the multivariable analogue of the usual derivative. It is covered in books like Michael Spivak's Calculus on Manifolds. Webp∈ (1,2) and q∈ (2,∞), or, the other way around, we can not apply the condition and we shall use a different argument. The idea to exploit the second derivative of the norm to analyse contrac-tive projections is not new. In fact, it already appears implicitly in work of Bernau and Lacey [2] and Lindenstrauss and Tzafriri [18], who considered
