Ron Aharoni is an Israel
i mathematician
, working in finite and infinite combinatorics
. Aharoni is a professor at the Technion – Israel Institute of Technology, where he received his Ph.D.
in mathematics in 1979. With Nash-Williams and Shelah
he generalized the marriage theorem by obtaining the right transfinite conditions for infinite bipartite graph
s. He subsequently proved the appropriate versions of the König theorem
and the Menger theorem for infinite graphs (the latter with Eli Berger).
Aharoni is the author of several nonspecialist books; the most successful is Arithmetic for Parents
, a book helping parents and elementary school teachers in teaching basic mathematics. He also wrote a book on the connections between Mathematics, poetry and beauty and a recent one on philosophy
(The Cat That is not There, both in Hebrew). His last to date book is "Man detaches meaning", on a mechanism common to jokes and poetry.

Bipartite graph
In the mathematical field of graph theory, a bipartite graph is a graph whose vertices can be divided into two disjoint sets U and V such that every edge connects a vertex in U to one in V; that is, U and V are independent sets...
