The existence of linear RT instability solutions with largest growth rate Λ is proved under the instability condition (i.e., the surface tension coefficient ϑ is less than a threshold ϑ c $\\vartheta …

Web6.2.2 Markov and Chebyshev Inequalities. Let X be any positive continuous random variable, we can write. = a P ( X ≥ a). P ( X ≥ a) ≤ E X a, for any a > 0. We can prove the above inequality for discrete or mixed random variables similarly (using the generalized PDF), so we have the following result, called Markov's inequality . for any a > 0. WebProof: Chebyshev’s inequality is an immediate consequence of Markov’s inequality. P(jX 2E[X]j t˙) = P(jX E[X]j2 t2˙) E(jX 2E[X]j) t 2˙ = 1 t2: 3 Cherno Method There are several re nements to the Chebyshev inequality. One simple one that is sometimes useful is to observe that if the random variable Xhas a nite k-th central moment then we ...
