The "shape" that forms an object and the "function" that an object exerts are closely related to each other. Dynamics describes how the shape and function of an object change over time. These changes appear as bifurcations and cooperative dynamics driven by nonlinear interactions between the elements that make up the object and interactions with external field. We aim to establish a methodology for ”microdynamics” by building models of multilayer structures and their interactions, and analyzing the model, and then verifying the theory.
