The College of Science, Department of Mathematics, has discussed a doctoral thesis entitled "On affinity groups of the Orlik-Solomon algebra for a graphically solvable Hebraic order" by postgraduate student Naaman Yassin Nema. The thesis aims to investigate the computation of the first non-zero covariance groups of the Orlik-Solomon algebra within the framework of graphical arrangements associated with hypersolvable graphs. By leveraging the topological duality of the conformal pairing between these graphs and their arrangements, along with matroid theory, the structural framework of A*(AG) for the graph order AG is transferred to reconstruct A*(G) directly from graph-theoretic data.
