Rayleigh inequality
Webuse a dual of the inequality of the Rayleigh quotients to obtain a bound on a derived linear program. Interestingly, that dual linear problem can be solved by using Monge sequences. … WebNov 11, 2024 · 1 Answer. Yes, to see this, we just have to let x be the all one vector. x T A x would sum up all the entries of A which gives us 2 e while x T x = n. @SionThyeGoh That's …

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 …
