SUMMARY

The discussion focuses on using the Rayleigh quotient to approximate the principal eigenvalue of the Sturm-Liouville problem defined by the equation u'' + (λ - x²)u = 0 with boundary conditions u(0) = 0 and u'(1) = 0. Participants emphasize the importance of integrating by parts after multiplying both sides by u to derive λ. The conversation highlights the need for clarity on the subsequent steps after this integration process.

PREREQUISITES
  • Understanding of Sturm-Liouville theory
  • Familiarity with the Rayleigh quotient
  • Knowledge of boundary value problems
  • Proficiency in integration techniques, particularly integration by parts
NEXT STEPS
  • Study the derivation of the Rayleigh quotient in the context of Sturm-Liouville problems
  • Explore numerical methods for approximating eigenvalues
  • Learn about boundary conditions and their impact on eigenvalue problems
  • Investigate advanced integration techniques relevant to differential equations
USEFUL FOR

Mathematicians, physicists, and engineers dealing with differential equations, particularly those focused on eigenvalue problems and boundary value analysis.

Use the Rayleight quotient to find a good approximation for the principal eigenvalue of the Sturm-Liouville problem.
u'' + (\lambda - x^2)u = 0
0 < x < 0
u(0) = u'(1) = 0
Any help?

Directions?


Back to the problem, I know that you multiply both sides by u, integrate by parts, and then solve for lambda, after that I'm stuck.
