Calculus of Variations - uni-leipzig.de

calculus of variations which can serve as a textbook for undergraduate and beginning graduate students. The main body of Chapter 2 consists of well known results concerning necessary or sufficient criteria for local minimizers, including Lagrange mul-tiplier rules, of real functions defined on a Euclidean n-space. Chapter 3

LECTURE 2: COMPLEX DIFFERENTIATION AND CAUCHY

LECTURE 2: COMPLEX DIFFERENTIATION AND CAUCHY RIEMANN EQUATIONS 3 (1) If f : C → C is such that f0(z) = 0 for all z ∈ C, then f is a constant function. This is because, by CR equation u x = u y = v x = v y = 0. So by MVT of two variable calculus u and v are constant function and hence so is f.

Potential Flow Theory - MIT

Equations (4.5) and (4.6) are known as the Cauchy-Riemann equations which appear in complex variable math (such as 18.075). Bernoulli Equation The Bernoulli equation is the most widely used equation in fluid mechanics, and assumes frictionless flow with no work or heat transfer. However, flow may or may not be irrotational.

5 Introduction to harmonic functions

connection to complex analysis. The key connection to 18.04 is that both the real and imaginary parts of analytic functions are harmonic. We will see that this is a simple consequence of the Cauchy-Riemann equations. In the next topic we will look at some applications to hydrodynamics. 5.2 Harmonic functions

The next theorem provides conditions under which the Cauchy-Riemann equations are sufficient for f(z) being holomorphic. Theorem 2.0.2: If the partial derivatives of U(x;y) and V(x;y) with respect to xand yare con-tinuous, the Cauchy-Riemann equations are sufficient for f(z) being holomorphic. Proof: See [Spiegel, 1974]. 2

– the Cauchy–Riemann equations. It is also possible to show that if the Cauchy–Riemann equations hold at a point z, then f is differentiable there (subject to certain technical conditions on the continuity of the partial derivatives). If we know the real part u of an analytic function, the Cauchy–Riemann equations

Equations (2, 3) are known as the Cauchy-Riemann equations. They are a necessary condition for f = u+iv to be analytic. 2.2 Necessary and sufficient conditions for a function to be analytic The necessary and sufficient conditions for a function f = u+iv to be analytic are that: 1. The four partial derivatives of its real and imaginary parts @u ...
