On the bifurcation theory of the Ginzburg-Landau equations

  title={On the bifurcation theory of the Ginzburg-Landau equations},
  author={'Akos Nagy and Gonccalo Oliveira},
A BSTRACT . We construct nonminimal and irreducible solutions to the Ginzburg–Landau equations on closed manifolds of arbitrary dimension with trivial first real cohomology. Our method uses bifurcation theory where the “bifurcation points” are characterized by the eigenvalues of a Laplace-type operator. To our knowledge these are the first such examples on nontrivial line bundles. 



Invariant connections and vortices

We study the vortex equations on a line bundle over a compact Kähler manifold. These are a generalization of the classical vortex equations over ℝ2. We first prove an invariant version of the theorem

Vortices in holomorphic line bundles over closed Kähler manifolds

We apply a modified Yang-Mills-Higgs functional to unitary bundles over closed Kähler manifolds and study the equations which govern the global minima. The solutions represent vortices in holomorphic

We show under natural assumptions that stable solutions to the abelian Yang--Mills--Higgs equations on Hermitian line bundles over the round $2$-sphere actually satisfy the vortex equations, which

Convergence of the self-dual $U(1)$-Yang-Mills-Higgs energies to the $(n-2)$-area functional

Given a hermitian line bundle L → M on a closed Riemannian manifold (M, g), the self-dual Yang–Mills–Higgs energies are a natural family of functionals

Irreducible Ginzburg–Landau Fields in Dimension 2

Ginzburg–Landau fields are the solutions of the Ginzburg–Landau equations which depend on two positive parameters, $$\alpha $$α and $$\beta $$β. We give conditions on $$\alpha $$α and $$\beta $$β for

Uhlenbeck Compactness

Preface The origin of this book lies at the beginning of my graduate studies, when I just could not understand Uhlenbeck compactness, let alone see whether it would also hold for my cases – on
