We will explore volume polynomials in three distinct settings: convex bodies, Hermitian matrices, and divisor classes on compact Kahler manifolds. After establishing their interrelations, we will leverage these connections to derive new inequalities for mixed volumes, mixed discriminants, and intersection numbers. Our results generalize classical inequalities, including the Alexandrov-Fenchel inequality and the reverse Khovanskii-Teissier inequality. Joint work with June Huh and Mateusz Michalek.
