On the second coefficient region for bounded univalent functions

On determining the points of the second coefficient body $(a_4,a_3,a_2)$ for bounded real univalent functions

“…The turning point in obtaining explicit results for bodies is the work done together with Kortram by using Grunsky type inequalities. The idea of this was first applied for (a s , 0 2 ) in S(b) [4] and was tested successfully for the second coefficient body in S R (b) yielding first algebraic parts of it [5]. However, in both cases the results remained partial and their completion needed much additional work and above all improving the inequalities available.…”
