Boolean Functions with Small Approximate Spectral Norm

Tsun-Ming Cheung, Hamed Hatami, Rosie Zhao +1

The sum of the absolute values of the Fourier coefficients of a function $f : F_{2}^{n} \to R$ is called the spectral norm of $f$ . Green and Sanders' quantitative versi…

On the peel number and the leaf-height of a Galton-Watson tree

Luc Devroye, Marcel K. Goh, Rosie Y. Zhao

We study several parameters of a random Bienaymé-Galton-Watson tree $T_{n}$ of size $n$ defined in terms of an offspring distribution $ξ$ with mean $1$ and nonzero finite variance $σ…

Leaf multiplicity in a Bienaymé-Galton-Watson tree

Anna M. Brandenberger, Luc Devroye, Marcel K. Goh +1

This note defines a notion of multiplicity for nodes in a rooted tree and presents an asymptotic calculation of the maximum multiplicity over all leaves in a Bienaymé-Galton-Watson…

Arithmetic subsequences in a random ordering of an additive set

Marcel K. Goh, Rosie Y. Zhao

For a finite set $A$ of size $n$ , an ordering is an injection from ${1, 2, \dots, n}$ to $A$ . We present results concerning the asymptotic properties of the length $L_{n}$ of the lon…
