Some new Bollobás-type inequalities

Erfei Yue

A family of disjoint pairs of finite sets $P = {(A_{i}, B_{i}) ∣ i \in [m]}$ is called a Bollobás system if $A_{i} \cap B_{j} \neq = \emptyset$ for every $i \neq = j$ , and a skew Bollobás…

On the structures of subset sums in higher dimension

Norbert Hegyvári, Máté Pálfy, Erfei Yue

A given subset $A$ of natural numbers is said to be complete if every element of $N$ is the sum of distinct terms taken from $A$ . This topic is strongly connected to the knapsack…
