A solution to the Furedi-Hajnal conjecture by Marcus & Tardos

How many 1's can there be in an n by n 0/1-matrix which avoids a certain fixed 0/1-matrix? Such a problem is related to Zarankiewicz problem in Extremal graph theory, and to Davenport-Schinzel theory which plays a great role in discrete and computational geometry.
Furedi & Hajnal ('92) conjectured if a given 0/1-matrix is a permutation matrix then the number of 1's is linear in n. Recently, Marcus & Tardos proved the conjecture affirmative in a quite simple way. In this talk, we are going to look at their proof, some consequences, and open problems.
