Notice

The course consists of the two parts [MAT-40-28-K-4] and [MAT-40-25-K-4].

In each summer semester at least one of the courses [MAT-40-30-K-4], [MAT-40-31-K-4] or [MAT-40-32-K-4] is offered.

Possible Study achievement

  • Verification of study performance: proof of successful participation in the exercise classes (ungraded)
  • Details of the examination (type, duration, criteria) will be announced at the beginning of the course.
    The certificate for the exercises ("Übungsschein") consists of the two (partial) certificates for the exercises in the courses [MAT-40-28-K-4] and [MAT-40-25-K-4].

Contents

Plane Algebraic Curves:

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,

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,

  • Further aspects of plane algebraic curves.

Character Theory of Finite Groups:

  • Maschke's theorem,
  • character tables,
  • orthogonality relations,
  • rationality questions,
  • Burnside theorem,
  • induced characters,
  • Frobenius groups.

Competencies / intended learning achievements

In the part "Plane Algebraic Curves", the students have learnt basic concepts of algebraic geometry by studying a class of algebraic varieties which is accessible by selected and simple methods.

In the part "Character Theory of Finite Groups", the students have studied the basic terms, propositions and techniques of representation theory through the character theory of finite groups. In particular, they have learnt to work with generic characters and character tables.
