111Elementary symmetric mean — The elementary symmetric mean is based on elementary symmetric polynomials.If x is a tuple with x = (x 1,dots,x n) andalpha p(x) is the corresponding elementary symmetric term of order p,then the respective mean is:M p(x) = sqrt [p] {frac{alpha… …
112Cesàro mean — In mathematics, the Cesàro means (also called Cesàro averages) of a sequence (an) are the terms of the sequence (cn), where is the arithmetic mean of the first n elements of (an). [1]:96 This concept is named after Ernesto Cesàro (1859 1906). A… …
