Complex $Γ$-convergence and magnetic Dirichlet Laplacian in bounded
thin tubes    [PDF]

R. Bedoya, C. R. de Oliveira, A. A. Verri

The resolvent convergence of self-adjoint operators via the technique of $\Gamma$-convergence of quadratic forms is adapted to incorporate complex Hilbert spaces. As an application, we find effective operators to the Dirichlet Laplacian with mag- netic fields in very thin bounded tubular regions in space built along smooth closed curves; the convergence is in the norm resolvent sense as the cross sections of the tubes go uniformly to zero.
