Would you like to see a short and interesting proof of Hahn-Banach extension theorem? In this talk, we shall discuss about partially ordered vector spaces, many examples and some linear preserver problems. I will present a very useful theorem from ordered vector space theory, \"M. Riesz extension theorem\". As an application of this theorem, we will prove the classical Hahn-Banach extension theorem.
