Advanced Engineering Mathematics, Lecture 4.1: Boundary value problems.
An initial value problem (IVP) is an ODE involving a function y(t) of time, with initial conditions. A boundary value problem (BVP) is an ODE involving a function y(x) of position, with boundary conditions. An example might be where y(x) measures the temperature of a rod, and the temperature at the endpoints is fixed. The theory of IVPs (existence and uniqueness of solutions) is well-understood, whereas BVPs are more mysterious. We give an 3 examples of an ODE with slightly different boundary conditions, yielding infinitely many, one, and no solutions, respectively. We conclude by solving a few variants of a classic BVP that will be very useful in our study of PDEs.
