Abstract

We study the limiting behavior as $\varepsilon$ tends to zero of the solution of a system arising in the microphase separation of diblock copolymers. This system involves a fourth-order parabolic equation. We consider the case of spherical symmetry, and we show the convergence to a free-boundary Hele--Shaw-type problem.
