The 25 pages that link to Asymptotic analysis, each with the reason it gives.
Random graphRelated: Many random graph theorems describe properties as the vertex count grows.
Catalan numberRelated: It gives the growth rate Cₙ ∼ 4ⁿ/(√π n³ᐟ²).
Mellin transformRelated: Poles of a Mellin transform encode terms in asymptotic expansions.
Donald KnuthRelated: Asymptotic notation expresses how algorithm costs grow with input size.
