Let G  be a finite group and let Irr(G)  be the set of irreducible characters of G . ‎We say that an element g  in G  is a vanishing element if there exists some χ∈ Irr(G)   such that χ(g)=0 ‎. In this paper, we provide a relatively short proof for the classification of finite groups whose set of vanishing elements is the :union: of exactly three conjugacy classes‎.


 
Keywords: conjugacy classes, irreducible characters, solvable groups, Frobenius groups, vanishing elements.
