"  Direct and Inverse Limits "
  Zhengyao Wu  


This talk will introduce briefly the direct (inductive) and the inverse (projective) limit motivated by the evolution of numbers from natural numbers to complex numbers. Examples cover algebraic closure of finite fields, abelianization of general linear groups, stalks, etc.
