Approximation Algorithms for Hypergraph Small Set Expansion and Small Set Vertex Expansion [PDF]

open access: yes, 2014
The expansion of a hypergraph, a natural extension of the notion of expansion in graphs, is defined as the minimum over all cuts in the hypergraph of the ratio of the number of the hyperedges cut to the size of the smaller side of the cut.

Fibonacci expansions

open access: yesRendiconti Lincei, Matematica e Applicazioni, 2021
Expansions in the Golden ratio base have been studied since a pioneering paper of Rényi more than sixty years ago. We introduce closely related expansions of a new type, based on the Fibonacci sequence, and we show that in some sense they behave better.

Re-examining the potential effectiveness of interactive query expansion [PDF]

open access: yes, 2003
Much attention has been paid to the relative effectiveness of interactive query expansion versus automatic query expansion. Although interactive query expansion has the potential to be an effective means of improving a search, in this paper we show that,

Fourier Expansions [PDF]

open access: yesProceedings of the Glasgow Mathematical Association, 1952
The theory of operational solutions of differential equations in applied mathematics suggests a method of developing the theory of Fourier and allied series that is simpler for ordinary applications than the classical development. It may be useful to those whose interests lie in such applications rather than in the deeper analytical processes ...
