... transform a sequence of du plicate and delete operations into a sequence of duplicate-delete operations of at most the same cos t. We follow the same steps, but t ransform the sequence into an a sequence ... current approaches for duplication analysis rely on heuristics, approximation algorithms, or restricted mod- els of duplication [3-7]. For example, there are efficient algor...

... We assume that T is a time scale. For t ∈ T, the forward jump operator σ : T → T is defined by σ(t) = inf{s ∈ T : s > t}, the backward jump operator ρ : T → T is defined by ρ(t) = sup{s ∈ T : s < ... function µ : T → [0, ∞) is defined by µ(t) = σ (t) − t. For other related basic concepts of time scales, we refer the reader to the original studies by Hilger [1–3], and for furt...
