Stability for hyperplane covers

Shagnik Das, Valjakas Djaljapayan, Yen-chi Roger Lin +1

An almost -cover of the hypercube is a collection of hyperplanes that avoids the origin and covers every other vertex at least times. When is large wit…

Graphlet and Orbit Computation on Heterogeneous Graphs

Colin Cleveland, Chin-Yen Lee, Shen-Fu Tsai +2

Many applications, ranging from natural to social sciences, rely on graphlet analysis for the intuitive and meaningful characterization of networks employing micro-level structures…

Semidefinite programming bounds for few-distance sets in the Hamming and Johnson spaces

Alexander Barg, Ching-Yi Lai, Pin-Chieh Tseng +1

We study the maximum cardinality problem of a set of few distances in the Hamming and Johnson spaces. We formulate semidefinite programs for this problem and extend the 2011 works…

Upper bounds for -distance sets and equiangular lines

Alexey Glazyrin, Wei-Hsuan Yu

The set of points in a metric space is called an -distance set if pairwise distances between these points admit only distinct values. Two-distance spherical sets with the se…

New bounds for equiangular lines and spherical two-distance sets

Wei-Hsuan Yu

A set of lines in is called equiangular if the angle between each pair of lines is the same. We derive new upper bounds on the cardinality of equiangular lines. Let…

Nonexistence of tight spherical design of harmonic index 4

Takayuki Okuda, Wei-Hsuan Yu

We give a new upper bound of the cardinality of a set of equiangular lines in with a fixed angle for each satisfying certain conditions. Our techniques are based…
