Implicit function theorem

When profit is being maximized, typically the resulting implicit functions are the labor demand function and the supply functions of various goods. The idea of the inverse function theorem is that if a function is differentiable and the derivative is invertible, the function is (locally) invertible. Let U ⊂ Rn be a set and let f: U → Rn be a continuously differentiable function. Also suppose x0 ∈ U, f(x0) = y0, and f ′ (x0) is invertible (that is, Jf(x0) ≠ 0). Implicit function theorem tells the same about a system of locally nearly linear (more often called differentiable) equations.

Recall that a mapping \(f \colon X \to X'\) between two metric spaces \((X,d)\) and \((X',d')\) is called a contraction if there exists a \(k < 1\) such that \[d'\bigl(f(x),f the Inverse Function Theorem, and it is easy to imagine that an implicit function theorem for Lipschitz functions might follow from the Inverse Function Theorem in the same way. However, there turns out to be a di culty. The most natural hypothesis for a Lipschitz implicit function theorem would be seem to be that every matrix A2 x 0 f should be an Then this implicit function theorem claims that there exists a function, y of x, which is continuously differentiable on some integral, I, this is an interval along the x-axis.

This is obvious in the one-dimensional case: if you have f (x;y) = 0 and you want y to be a function of x; then you Derivatives of Implicit Functions Implicit-function rule If a given a equation , cannot be solved for y explicitly, in this case if under the terms of the implicit-function theorem an implicit function is known to exist, we can still obtain the desired derivatives without having to solve for first. The Implicit Function Theorem: Let F : Rn Rm!Rn be a C1-function and let (x; ) 2 Rn Rm be a point at which F(x; ) = 0 2Rn. If the derivative of Fwith respect to x is nonsingular | i.e., if the n nmatrix @F k @x i n k;i=1 is nonsingular at (x; ) | then there is a C1-function f: N !Rn on a neighborhood N of that satis es (a) f( ) = x, i.e., F(f( ); ) = 0, Implicit Function Theorem Suppose that F(x0;y0;z0)= 0 and Fz(x0;y0;z0)6=0. Then there is function f(x;y) and a neighborhood U of (x0;y0;z0) such that for (x;y;z) 2 U the equation F(x;y;z) = 0 is equivalent to z = f(x;y). Ex A special case is F(x;y;z) = f(x;y)¡az = 0.
