We consider the magnetic Ginzburg-Landau equations informally corresponding to the Euler-Lagrange equations for the energy functionalHere u : R 4 → C, A : R 4 → R 4 and d denotes exterior derivative when A is regarded as a 1-form in R 4 . Given a 2-dimensional minimal surface M in R 3 with finite total curvature and non-degenerate, we construct a solution (uε, Aε) which has a zero set consisting of a smooth 2-dimensional surface close to M × {0} ⊂ R 4 . Away from the latter surface we have |uε| → 1 andfor all sufficiently small z = 0. Here y ∈ M and ν(y) is a unit normal vector field to M in R 3 .
We consider the magnetic Ginzburg-Landau equations in a compact manifold Nformally corresponding to the Euler-Lagrange equations for the energy functionalHere u : N → C and A is a 1-form on N . Given a codimension-2 minimal submanifold M ⊂ N which is also oriented and non-degenerate, we construct a solution (uε, Aε) such that uε has a zero set consisting of a smooth surface close to M . Away from M we haveas ε → 0, for all sufficiently small z = 0 and y ∈ M . Here, {ν 1 , ν 2 } is a normal frame for M in N . This improves a recent result by De Philippis and Pigati [10] who built a solution for which the concentration phenomenon holds in an energy, measure-theoretical sense.We consider a closed, n-dimensional manifold N n and a closed n − 2-dimensional minimal submanifold M n−2 ⊂ N n . We say that a minimal manifold. We also require that M is non-degenerate, in the sense that the Jacobi operator has trivial bounded kernel, namely(1.6)We recall that the Jacobi operator is the second variation of the area functional around M , namelyNow we state the main result.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
