Block structure in boolean matrices of bounded factorization norm

Marcel K. Goh, Hamed Hatami

A boolean matrix is blocky if its $1$ -entries form a collection of 1-monochromatic submatrices that are disjoint in both rows and columns. Blocky matrices are precisely the set of…

Block complexity and idempotent Schur multipliers

Marcel K. Goh, Hamed Hatami

We call a matrix blocky if, up to row and column permutations, it can be obtained from an identity matrix by repeatedly applying one of the following operations: duplicating a row,…

A note on plane trees with decreasing labels

Tsun-Ming Cheung, Luc Devroye, Marcel K. Goh

This note derives asymptotic upper and lower bounds for the number of planted plane trees on $n$ nodes assigned labels from the set ${1, 2, \dots, k}$ with the restriction that on…
