Root separation for irreducible integer polynomials
Yann Bugeaud, Andrej Dujella · Bulletin of the London Mathematical Society · 2011
We establish new results on root separation of integer, irreducible polynomials of degree at least 4. These improve earlier bounds of Bugeaud and Mignotte (for even degree) and of Beresnevich, Bernik, and Götze (for odd degree).
