0.4 Singular Boundary Value Problems

0.4 Singular Boundary Value Problems

  • The differential equation is subject to these conditions.
  • There are two ways in which a boundary value problem can be singular.
    • A singular point of the differential equation is the endpoint of the interval of interest.
    • The interval is long in the other.

  • A regular singular point is 0 Section 1 of the equation has a regular singular point at the origin.
  • A boundary point is a mathematical boundary without being a physical boundary.
    • The mathematical boundary is in the interior of the disk.
  • We enforce the condition explicitly when a singular point is a boundary point.
    • In the example that follows, we will see how these conditions act to make the solution of a boundary value problem unique.
  • Only the physical boundary condition has been noted.

  • The differential equation is easy to solve.

  • An ordinary boundary condition works at an ordinary point.
    • The second boundary condition determines 2.
  • The interval of interest is infinite in a singular boundary value problem.
    • No boundary condition is imposed at the other end.

  • Add the appropriateBoundedness condition to solve the problem.

  • Provide and solve the properBoundedness condition.
  • The boundary of the sphere has a 0.
    • Section 0.1 is called Exercise 19.
