Abstract: This will be an accessible introductory talk on the theory of quasi-determinants of Gelfand--Retakh and how they can be used to define analogue of symmetric functions over free non-commutative skew-fields. In particular, there are many different bases for the Hopf algebra of non-commutative symmetric functions giving analogues to the classical bases of elementary symmetric functions, complete homogeneous functions, power sums, or Schur functions.
