题目：Antimagic Labeling of Biregular Bipartite Graphs

主讲人：于筱蔚

摘要：An antimagic labeling of a graph $G$ with $n$ vertices and $m$ edges is a bijection from the set of edges of $G$ to the integers $\{1,2, \cdots,  m\}$ such that all $n$ vertex sums are pairwise distinct, where the vertex sum of a vertex is the sum of labels of all edges incident to it. A graph $G$ is antimagic if $G$ has an antimagic labeling. Hartsfield and Ringel conjectured that every connected graph other than $K_2$ is antimagic, which is commonly referred to as Antimagic Labeling Conjecture.  In this talk, I shall introduce some known results and the proof of antimagic labeling of biregular bipartite graph.
