Minimum degrees for powers of paths and cycles

We study minimum degree conditions under which a graph $G$ contains $k$th powers of paths and cycles of arbitrary specified lengths. We determine precise thresholds, assuming that the order of $G$ is large. This extends a result of Allen, B"ottcher and Hladk'y [J. Lond. Math. Soc. (2) 84(2) (2011), 269–302] concerning the containment of squares of paths and squares of cycles of arbitrary specified lengths and settles a conjecture of theirs in the affirmative.
