Derivatives

zeta-ic adj. /ziːˈteɪɪk/ Mathematics (Obsolete rare) in or with reference to the work of English mathematician J. J. Sylvester (1814–97): designating multiplication in which the product between two quantities denoted by the same letter but having different subscript indices is a quantity denoted by the same letter which has the sum of these indices as its index; (also) designating a product or function involving such multiplication.In essence, zetaic multiplication treats the indices as if they were powers. For example, the product of a1 and a3 is a4, but the product of a1 and b3 is a1b3.
