Calculus of Variations solved problems. Pavel Pyrih. June 4, 2012. ( public domain ). Acknowledgement. The following problems were solved using my own procedure in a program Maple V, release 5. All possible errors are my faults. 1 Solving the Euler equation. Theorem.(Euler) Suppose f(x, y, y ) has continuous partial
v(x). Comparing P(u) with P(u+v), the linear term in the difference yields ?P/?u. This linear term must be zero for every admissible v (weak form). This program carries ordinary calculus into the calculus of variations. We do it in several steps: 1. One-dimensional problems P(u) = ? F(u, u?) dx, not necessarily quadratic. 2.
Let X and Y be two arbitrary sets and f : X > Y be a well-defined function having domain. X and range Y . The function values f(x) become comparable if Y is IR or a subset of IR. Thus, optimization problem is valid for real valued functions. Let f : X > IR be a real valued function having X as its domain. Now x0 ? X is said to

CALCULUS OF VARIATIONS. PROF. ARNOLD ARTHURS. 1. Introduction. Example 1.1 (Shortest Path Problem). Let A and B be two fixed points in a space. Then we want to find the shortest distance between these two points. We can construct the problem diagrammatically as below. A. B a b x. Y = Y (x) ds dx. dY. Figure 1.
Chapter 1. Introduction. A huge amount of problems in the calculus of variations have their origin in physics where one has to minimize the energy associated to the problem under consideration. Nowadays many problems come from economics. Here is the main point that the resources are restricted. There is no economy.
