Título:
Rationality of quotient varieties

Abstract:
The rationality problem in algebraic geometry asks whether a given irreducible
variety is birational to a projective space. We will gently introduce the
problem and take a look at some recent advances, principally in the direction
of negative examples constructed via cohomological obstructions. Special focus
will be set on quotient varieties by linear group actions.
