The coefficients c i are given by the elementary symmetric polynomials of the eigenvalues of A.Using Newton identities, the elementary symmetric polynomials can in turn be expressed in terms of power sum symmetric polynomials of the eigenvalues: = = = (), where tr(A k) is the trace of the matrix A k.
D&H use the Helmholtz and Gibbs free entropies and to express the effect of electrostatic forces in an electrolyte on its thermodynamic state. Specifically, they split most of the thermodynamic potentials into classical and electrostatic terms: Φ = S − U T = − A T , {\displaystyle \Phi =S-{\frac {U}{T}}=-{\frac {A}{T}},} where
