Eigenvalue problems of Ginzburg–Landau operator in bounded domains
Kening Lu, Xing‐Bin Pan · Journal of Mathematical Physics · 1999
In this paper we study the eigenvalue problems for the Ginzburg–Landau operator with a large parameter in bounded domains in R2 under gauge invariant boundary conditions. The estimates for the eigenvalues are obtained and the asymptotic behavior of the associated eigenfunctions is discussed. These results play a key role in estimating the critical magnetic field in the mathematical theory of superconductivity.
