WebAug 1, 2024 · Derivative of the conjugate of a function complex-analysis 8,856 In all non-trivial cases the conjugate of a complex-differentiable function is not complex-differentiable itself, so it makes no sense talking about its derivative. To see this, let f ( z) be a non-constant complex-differentiable function. WebApr 7, 2024 · Secure Your Seat. Crypto derivatives exchange dYdX said Friday it is exiting the Canadian market.

In mathematics and mathematical optimization, the convex conjugate of a function is a generalization of the Legendre transformation which applies to non-convex functions. It is also known as Legendre–Fenchel transformation, Fenchel transformation, or Fenchel conjugate (after Adrien-Marie … See more For more examples, see § Table of selected convex conjugates. • The convex conjugate of an affine function $${\displaystyle f(x)=\left\langle a,x\right\rangle -b}$$ is f ∗ ( x ∗ ) = { b , x ∗ = a + ∞ , x ∗ ≠ a . … See more • Touchette, Hugo (2014-10-16).
