报告摘要:Motivated by emerging applications in coding for molecular data storage, much attention has been paid to the intersecting set discrepancy problem, which aims to design a large family of subsets of a common labeled ground set with bounded pairwise intersection and bounded set discrepancy. In this talk, we study the maximum size of such families of $k$-subsets with $v$ elements ground set, $t$-bounded intersections, and zero or one discrepancy, called as balanced $(t,k,v)$ set codes. We constructed optimal balanced $(t,k,v)$ set codes for $(t,k) = (2,3),(2,4),(3,4)$, and proven that there exists asymptotically optimal balanced $(t,k,v)$ set codes for any fixed integers $2 \leq t < k$.
