Abstract:
An ingenious generalization of univalent functions of one complex variable into matrix functions was introduced by B. Schwarz, along with two conjectures corresponding to the first coefficient problem and the second coefficient problem for the traditional classes $\Sigma$ and $S$, respectively. We exhibit two counterexamples for these conjectures.References
