Abstract: Energy-driven pattern formation examines how energy minimization leads to the formation of defects and microstructure in a variety of physical systems. Examples include the wrinkling of a stretched elastic membrane, the twinning produced by martensitic phase transformation, and the defects seen in liquid crystals. In these and many other examples, the physics is modelled by a nonconvex variational problem regularized by a higher-order term with a small coefficient, and energy-driven pattern formation can be studied by considering the limiting behavior of minimizers as the small parameter tends to zero. Another recurrent theme is the use of ansatz-free bounds to identify and explore the features of energy-minimizing configurations. A third recurrent theme is dynamics, since the patterns of interest are sometimes transient states of steepest-descent processes.
