Abraham Ziv (March 6, 1940–March 5, 2013 (aged 72)) was an Israeli mathematician, known for his contributions to the Zero-sum problem as part of the discoverers of the Erdős–Ginzburg–Ziv theorem.

Life

He was born in Avihayil, Israel in the 1940s to Haim and Zila Zubkovski. Like many other Israeli-Jews of his time, he changed his surname in the 1950s to Ziv, as part of the popular Hebraization of surnames movement. Abraham studied at the Technion – Israel Institute of Technology, where he earned his Ph.D., in mathematics, after receiving his master's degree from Harvard University a few years earlier. In 1961, at the age of 21, he proved along with Paul Erdős and Abraham Ginzburg the general result that every sequence of $2n-1\$ elements of $\mathbb {Z} /n\mathbb {Z}$ contains $n$ terms that sum to zero.^[1]

In 1972 Ziv was part of the founding team of IBM R&D Labs in Israel, where he stayed until retirement. In his time at IBM he wrote 21 more publications^[2] and 6 patents that are still owned by IBM to this day.^[3]
