Supersaturation for Eventown via Generator Switching

Zicheng Han, Xiande Zhang, Yuhao Zhao

An eventown family is a family of even-sized subsets of in which every two distinct members have an even-sized intersection. A classical theorem of Berlekamp and Graver shows…

Bounds and constructions for constant/low-power error-correcting cooling codes

Shuangqing Liu, Tingting Tong, Menglong Zhang +2

The low-power error-correcting cooling (LPECC) codes and constant-power error-correcting cooling (CPECC) codes, introduced in [IEEE Trans. Inf. Theory, 64 (2018), 3062--3085; 66 (2…

A superlogarithmic saving for Oddtown modulo composite numbers

Yuhao Zhao

Let be the largest size of a family such that no member has size divisible by , while the intersection of every two distinct membe…

Lower bounds on the strength of the determinant

Qiyuan Chen, Yuhao Zhao

We establish new lower bounds for the strength and partition rank of the determinant. For every prime , we prove the exact identity \[ \operatorname{str}(\mathrm{det}_p)=p. \] A…

Counting cliques with prescribed intersection sizes

Yuhao Zhao, Xiande Zhang

We study the generalized Turán problem regarding cliques with restricted intersections, which highlights the motivation from extremal set theory. Let $L=\{\ell_1,\dots,\ell_s\}\sub…

On low-power error-correcting cooling codes with large distances

Yuhao Zhao, Xiande Zhang

A low-power error-correcting cooling (LPECC) code was introduced as a coding scheme for communication over a bus by Chee et al. to control the peak temperature, the average power c…

Focal-free uniform hypergraphs and codes

Xinqi Huang, Chong Shangguan, Xiande Zhang +1

Motivated by the study of a variant of sunflowers, Alon and Holzman recently introduced focal-free hypergraphs. In this paper, we show that there is an interesting connection betwe…

Improved upper bounds for wide-sense frameproof codes

Yuhao Zhao, Xiande Zhang

Frameproof codes have been extensively studied for many years due to their application in copyright protection and their connection to extremal set theory. In this paper, we invest…

On supersaturation for oddtown and eventown

Xin Wei, Yuhao Zhao, Xiande Zhang +1

We study the supersaturation problems of oddtown and eventown. Given a family of subsets of an element set, let denote the number of distinct pair…
