AI总结:

本文发现超立方体的顶点Turán型问题与erasure list-decodable codes等价,通过分析近期构造并确定超图增广的Turán密度,获得了部分问题的改进界。

摘要:

我们观察到,超立方体的几个备受组合学界关注的顶点Turán型问题等价于关于erasure list-decodable codes的问题。通过分析Ellis、Ivan和Leader近期的一个构造,并确定某些超图增广的Turán密度,我们获得了其中部分问题的改进界。

英文摘要:

We observe that several vertex Turán type problems for the hypercube that received a considerable amount of attention in the combinatorial community are equivalent to questions about erasure list-decodable codes. Analyzing a recent construction of Ellis, Ivan and Leader, and determining the Turán density of certain hypergraph augemntations we obtain improved bounds for some of these problems.
