Cauchy-Riemann equation
(mathematics, complex analysis, always plural) Given a complex-valued function f and real-valued functions u and v such that f(z) = u(z) + iv(z), either of the equations (∂u)/(∂x)=(∂v)/(∂y) or (∂u)/(∂y)=-(∂v)/(∂x), which together form part of the criteria that f be complex-differentiable.
Flory-Fox equation
(chemistry) In polymer chemistry, a simple empirical formula that relates molecular weight to the glass transition temperature of a polymer system.
absolute personal equations

The difference between an observed value and a standard value assumed as true.
Henderson-Hasselbalch equation
(chemistry) An equation describing the derivation of pH as a measure of acidity (using pKa, the negative log of the acid dissociation constant) in biological and chemical systems.
Volterra integral equations
Lotka-Volterra equation
Either of a pair of first-order nonlinear differential equations that are frequently used to describe the dynamics of biological systems in which two species interact, one as a predator and the other as prey.
