AbstractThe Aleksandrov-Fenchel inequalities from the theory of mixed volumes are used to prove that certain sequences of combinatorial interest are log concave (and therefore unimodal)
The Alexandrov-Fenchel inequality bounds from below the square of the mixed volume V (K1,K2,K3, Kn) ...
The LYM property of a finite standard graded poset is one of the central notions in Sperner theory. ...
We prove that two infinite families of polynomials naturally associated to Fibonacci Lattices have o...
