Abstract
A partition of a positive integer \(n\) is a non-increasing sequence of positive integers whose sum is \(n\). It may be represented by a Ferrers diagram. These diagrams contain corners which are points of degree two. We define corners of types \((a,b)\), \((a+,b)\) and \((a+,b+)\), and also define the size of a corner. Via a generating function, we count corners of each type and corners of size \(m\). We also find asymptotics for the number of corners as \(n\) tends to infinity.
