abstract = {<p style="text-align: justify;">We consider a C0 interior penalty finite element approximation of a sixth-order
Cahn-Hilliard type equation that models the dynamics of phase transitions in ternary oil-water-surfactant systems. The nonlinear sixth-order parabolic equation is expressed in a mixed form
whereby a second-order (in space) parabolic equation and an algebraic fourth-order (in space)
nonlinear equation are considered. The temporal discretization is chosen so that a discrete energy
law can be established leading to unconditional energy stability. Additionally, we show that
the numerical method is unconditionally uniquely solvable. We conclude with several numerical
experiments demonstrating the unconditional stability and first-order accuracy of the proposed
method.</p>},
