Note on sunflowers

چکیده

A sunflower with p petals consists of sets whose pairwise intersections are identical. The goal the problem is to find smallest r=r(p,k) such that any family rk distinct k-element contains a petals. Building upon breakthrough Alweiss, Lovett, Wu and Zhang from 2019, Rao proved r=O(plog(pk)) suffices; this bound was reproved by Tao in 2020. In short note we record r=O(plogk) suffices, using minor variant probabilistic part these recent proofs.

Sunflowers in Lattices

A Sunflower is a subset S of a lattice, with the property that the meet of any two elements in S coincides with the meet of all of S. The Sunflower Lemma of Erdös and Rado [2] asserts that a set of size at least 1 + k!(t − 1)k of elements of rank k in a Boolean Lattice contains a sunflower of size t. We develop counterparts of the Sunflower Lemma for distributive lattices, graphic matroids, and...

William Pickles lecture 1989. Seeing sunflowers.

THE clearest memory I have from my first year as a medical student is of a botany practical. We had the task, one sunny Thursday afternoon, of cutting a very thin slice of a sunflower stem, putting it under the microscope and drawing what we saw. In the textbook there was an illustration of what we should expect to see: as I remember, it showed regular, neatly-'packed cells with several smaller...

Rapid hybrid speciation in wild sunflowers.

Hybrid or "recombinational" speciation refers to the origin of a new homoploid species via hybridization between chromosomally or genetically divergent parental species. Theory predicts that this mode of speciation is punctuated, but there has been little empirical evidence to support this claim. Here, we test the hypothesis of rapid hybrid speciation by estimating the sizes of parental species...

Lower Bounds on Non-Adaptive Data Structures Maintaining Sets of Numbers, from Sunflowers

We prove new cell-probe lower bounds for dynamic data structures that maintain a subset of {1, 2, ..., n}, and compute various statistics of the set. The data structure is said to handle insertions non-adaptively if the locations of memory accessed depend only on the element being inserted, and not on the contents of the memory. For any such data structure that can compute the median of the set...
