The Absence of Residual Property for Total Hyper-Frequencies of Solutions to Third Order Differential Equations / A. Kh. Stash. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2017. № 2. P. 65-68 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 81-83].

It is established that total hyper-frequencies considered as functionals on the set of solutions to third order homogeneous linear differential equations with continuous coefficients bounded on the semiaxis are not residual (i.e. can be changed when changing the solution on a finite interval).

Key words: linear differential equation, oscillation of solution, zeroes of function, characteristic frequency, complete frequency.
