WebRayleigh’s method The above equation can be used to find an approximate value of the first natural frequency of the system. For this, we select a trial vector X to represent the first natural mode X(1) and substitute it on the right hand side of the above equation. This yields the approximate value of ω1 2.

In spectral geometry, the Rayleigh–Faber–Krahn inequality, named after its conjecturer, Lord Rayleigh, and two individuals who independently proved the conjecture, G. Faber and Edgar Krahn, is an inequality concerning the lowest Dirichlet eigenvalue of the Laplace operator on a bounded domain in , . It states that the first Dirichlet eigenvalue is no less than the corresponding Dirichlet eigenvalue of a Euclidean ball having the same volume. Furthermore, the inequality is rigid in the … In mathematics, the Rayleigh quotient for a given complex Hermitian matrix M and nonzero vector x is defined as: For real matrices and vectors, the condition of being Hermitian reduces to that of being symmetric, and the conjugate transpose $${\displaystyle x^{*}}$$ to the usual transpose See more An empirical covariance matrix $${\displaystyle M}$$ can be represented as the product $${\displaystyle A'A}$$ of the data matrix $${\displaystyle A}$$ pre-multiplied by its transpose $${\displaystyle A'}$$. … See more • Field of values • Min-max theorem • Rayleigh's quotient in vibrations analysis • Dirichlet eigenvalue See more Sturm–Liouville theory concerns the action of the linear operator This is sometimes presented in an equivalent form, obtained by separating the integral in the … See more 1.
