Normality vs. extremal disconnectedness: two sandwich-type results for the price of one
 
 
Description:  Several results in the literature about normal and extremally disconnected spaces (like Katetov-Tong type theorems, Uryshon's type lemmas or Tietze's type lemmas) shape the idea that the two notions are somehow dual to each other and therefore can be studied in parallel.
In this talk we will discuss the source of this 'duality' and show how each pair of parallel results can be framed by the same proof. The key idea appears to be, once more, "generalize, to understand better".
