The Chair of Algebra and Number Theory of the Faculty of Mathematics is looking for a 

PhD-Student (m,f,x) for 3 years, 29,8725 hour per week

Research and teaching at the chair is conducted in algebra, predominantly in algebraic Lie Theory, specifically algebraic groups, finite groups of Lie and various aspects of hyperplane arrangements.

Research within the DFG-project on hyperfactored and recursively factored arrangements

extent: part-time
duration: temporary
beginning: as soon as possible
application deadeline:

Your tasks:

  • Conduct research within the DFG-project on hyperfactored and recursively factored arrangements, prepare dissertation and publications in connection with the project.

Your profile:

  • Applicants should hold, or be about to complete, a relevant academic degree (e.g. Master) in a relevant mathematical subject area in algebra, combinatorics or computer science. Research experience in combinatorics, hyperplane arrangements and programming experience will be an advantage, but is not essential. The DFG-project deals with combinatorial questions evolving around the notion of factored hyperplane arrangements.

Our offerings:

  • Challenging and varied tasks with a high degree of personal responsibility
  • Team-oriented cooperation in a committed, international and appreciative team

- a detailed Curriculum Vitae,
- addresses of up to three academics who may be contacted to obtain academic references,
- (electronic) copies of relevant papers, degree certificates, and theses, as relevant

The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is RUB’s declared aim.

The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
