摘要
For each , Roulleau and UrzAa give an implicit construction of a configuration of complex plane cubic curves. This construction was crucial for their work on surfaces of general type. We make this construction explicit by proving that the Roulleau-UrzAa configuration consists precisely of the Halphen cubics of order m, and we determine specific equations of the cubics for (which were known) and for (which are new).
