We present notes on the Marcus-de Oliveira conjecture. The conjecture concerns the region in the complex plane covered by the determinants of the sums of two normal matrices with prescribed eigenvalues. Call this region ∆. This paper focuses on boundary matrices of ∆. We prove 4 theorems regarding these boundary matrices. We propose 2 conjectures related to the Marcus-de Oliveira conjecture.
