Funções simétricas e combinatória

TL;DRAbstract

This work is divided in two parts. In the first one, we present the symmetric functions: the symmetric functions vector space over the field of the rational numbers, some bases, an inner product and the so called Schur (symmetric) functions. In the second part, we present some of the many aplications of this theory: in the study of the characters of the symmetric group's representations; in the plane partitions; in permutation enumeration; in the enumeration under group action.
