Estimates for the norms of fractional derivatives in terms of integral moduli of continuity and their applications
For functions defined on the real line or a half-line, we obtain Kolmogorov-type inequalities that estimate the $L_p$-norms $(1 \leq p < \infty)$ of fractional derivatives in terms of the Lp-norms of functions (or the $L_p$-norms of their truncated derivatives) and their $L_p$-moduli of conti...

Ukrains’kyi Matematychnyi Zhurnal| Zusammenfassung: | For functions defined on the real line or a half-line, we obtain Kolmogorov-type inequalities that estimate the
$L_p$-norms $(1 \leq p < \infty)$ of fractional derivatives in terms of the Lp-norms of functions (or the $L_p$-norms of their truncated derivatives) and their $L_p$-moduli of continuity and establish their sharpness for $p = 1$.
Applications of the obtained inequalities are given. |
