Here, the author continues studies in [Differ. Equ. 35, No. 12, 1619-1633 (1999); translation from Differ. Uravn. 35, No. 12, 1597-1609 (1999; Zbl 0974.34078)], where the rate of equiconvergence with the trigonometric series for biorthogonal expansions in root functions of a differential operator of arbitrary order was considered in the metric of \(L_s\), \(s>1\), on any compact subset of the considered interval.
