Cybern. 36, No. 2, 92-100 (2012); translation from Vestn. Mosk. Univ., Ser. XV 2012, No. 2, 37-43 (2012).} \itemab Summary: This work is devoted to the properties of transformations of the vector of values of three-value logic functions to the vector of coefficients of their polynomials. A similar transformation of Boolean functions is used in cryptology, and its properties have been thoroughly studied. Stationary classes of three-value logic functions are introduced, and their hierarchy and the exact number of functions in them are obtained. \itemrv{~} \itemcc{} \itemut{three-value logic functions; polynomials; M\"obius transformation} \itemli{doi:10.3103/S0278641912010050} \end
