Liquid and gas contributions determined by amoeba geometry

Let P(z,w)=kp(z,w)P(z,w)=k-p(z,w) be a Newton polynomial with fixed p(z,w)p(z,w). Let ml(P)m_l(P) and mg(P)m_g(P) denote the liquid and gas contributions to the Mahler measure, and let A(P)\mathcal{A}(P) be the amoeba, with area A(A)A(\mathcal{A}) and total hole area AhA_h. Phase-contribution conjecture. The liquid contribution ml(P)m_l(P) is determined only by A(A)A(\mathcal{A}), while the gas contribution mg(P)m_g(P) is determined only by AhA_h. This proposed decomposition aims to relate the two phase contributions along the Mahler flow to the corresponding amoeba geometry; the source does not prove the asserted dependence.
