Stability analysis of polarized domains

Abstract
Polarized ferrofluids, lipid monolayers, and magnetic bubbles form domains with deformable boundaries. Stability analysis of these domains depends on a family of nontrivial integrals. We present a closed-form evaluation of these integrals as a combination of Legendre functions. This result allows exact and explicit formulas for stability thresholds and growth rates of individual modes. We also evaluate asymptotic behavior in several interesting limits.
