Abstract:
Variational principles involving nonlocal terms are well-established for
governing certain pattern morphologies in ferromagnetism and type-I
superconductivity. Recently, a nonlocal functional has also been
introduced to
describe microphase separation in diblock copolymer melts. In this talk,
I will
address some basic issues surrounding the variational problems and associated
pattern morphologies, and then  discuss the application of some new
mathematical tools. I will focus mostly on domain structures in uniaxial
ferromagnets and microphases of diblock copolymers.
