✦ Synopsis

Abstract

The coronal loop problem is characterized by mixed boundary conditions and the loop length condition, which is global. Using singular perturbation methods one can identify and construct two boundary layers at the base of the loop.

Extending this to a combined asymptotic‐numerical treatment it is possible to construct two static solutions satisfying the same conditions; this unusual feature arises from the presence of the first boundary layer, which corresponds with a steep temperature gradient and an energy balance dominated by conduction and radiation losses.

## Abstract We consider a boundary problem for an elliptic system in a bounded region Ω ⊂ ℝ^__n__^ and where the spectral parameter is multiplied by a discontinuous weight function __ω__ (__x__) = diag(__ω__~1~(__x__), …, __ω~N~__ (__x__)). The problem is considered under limited smoothness assump
