Improved Formula Size Lower Bounds for Monotone Self-Dual Boolean Functions
Kenya Ueno (Univ. of Tokyo) COMP2008-51
Abstract (in Japanese) (See Japanese page) 
(in English) We introduce a new technique proving formula size lower bounds based on the linear programming bound originally introduced by Karchmer, Kushilevitz and Nisan~\cite{KKN95} and the theory of stable set polytope. We apply it to majority functions and prove their formula size lower bounds improved from the classical result by Khrapchenko~\cite{Khrapchenko71}. Moreover, we introduce a notion of unbalanced recursive ternary majority functions motivated by a decomposition theory of monotone self-dual functions and give integrally matching upper and lower bounds of their formula size. We also show monotone formula size lower bounds of balanced recursive ternary majority functions improved from the quantum adversary bound of Laplante, Lee and Szegedy~\cite{LLS06}.
