Abstract

From traditional convex systems to general nonlinear systems, we will study, in this chapter, the generalized duality theory and analytic solutions for one-dimensional nonconvex variational problems with applications to phase transitions, post-bifurcation, nonsmooth elastoplasticity and nonconvex dynamical systems. Because of the nonconvexity, the nice simple symmetry in the governing equations is broken and the beautiful one-to-one global duality relation no longer exists. The solutions in these systems are usually not unique. But, by introducing a suitable nonlinear operator A, a generalized framework may still be established for many systems. The resulting triality theory reveals interesting local dualities (see Fig. 3.1, the associated problem is given in Example 3.3).
