Possible Study achievement

  • Verification of study performance: proof of successful participation in the exercise classes (ungraded)
  • Examination number (Study achievement): 84009 ("Exercise Class Plane Algebraic Curves")
  • Details of the examination (type, duration, criteria) will be announced at the beginning of the course.


Compulsory Topics:
  • Affine and projective spaces, in particular, the projective line and the projective plane,
  • Plane algebraic curves over the complex numbers,
  • Smooth and singular points,
  • Bézout's Theorem for projective plane curves,
  • Topological genus of a curve and the genus formula,
  • Rational maps between plane curves and the Riemann-Hurwitz formula.

In addition, a selection of the following topics is covered:

  • Polar and Hessian curves,
  • Dual curves and Plücker’s formulas,
  • Linear systems and divisors on smooth curves,
  • Real projective curves,
  • Puiseux-parameterizations of plane curve singularities,
  • Invariants of plane curve singularities,
  • Elliptic curves,
  • Further aspects of plane algebraic curves.

Competencies / intended learning achievements

The students have studied and understand basic concepts of algebraic geometry in a selected and easily accessible class of algebraic varieties.


  • G. Fischer: Ebene algebraische Kurven,
  • E. Brieskorn, H. Knörrer: Plane Algebraic Curves,
  • E. Kunz: Introduction to Plane Algebraic Curves,
  • F. Kirwan: Complex Algebraic Curves,
  • R. Miranda: Algebraic Curves and Riemann Surfaces.


Further literature will be announced in the lecture; Exercise material is provided.

Requirements for attendance (informal)

More advanced knowledge from the courses [MAT-12-22-K-3] und [MAT-12-26-K-3] is useful but not necessarily required.
