The Ruhr-Universität Bochum is one of the leading research universities. The university draws its strengths from both the diversity and the proximity of  scientific and engineering disciplines on a single, coherent campus. This highly dynamic setting enables students and researchers to work across traditional boundaries of academic subjects and faculties.

The research to be undertaken in the DFG-funded PhD position is concerned with questions relating to the Cohomology of complements of complex reflection arrangements.

The theory of hyperplane arrangements has been a driving force in mathematics over many decades. It naturally lies at the crossroads of algebra, combinatorics, algebraic geometry, representation theory and topology. This research to be untertaken within this DFG-funded post in turn lies at the very heart of these subject matters. Deep and remarkable connections have been discovered over the years between the topology of the complement M(A) of an arrangement A, the freeness of the module of derivations D(A) of A and the combinatorics of the intersection lattice L(A) of A consisting of the subspaces arising as intersections of hyperplanes from A. The study of the complement of complex hyperplane arrangements has a long and remarkably rich history.

The position is third party funded and does not have any formal teaching duties attached.
