TLDR
In this article, the geometric structures of configurations with a pair of type A and B nulls permit reconnection across the null-null lines; these are the field lines which join the two nulls.
Abstract
The present investigation of three-dimensional reconnection of magnetic fields with nulls and of fields with closed lines gives attention to the geometry of the former, with a view to their gamma-line and Sigma-surface structures. The geometric structures of configurations with a pair of type A and B nulls permit reconnection across the null-null lines; these are the field lines which join the two nulls. Also noted is the case of magnetostatic reconnection, in which the magnetic field is time-independent and the electrostatic potential is constant along field lines.

Three-dimensional magnetic reconnection without null points: 1. Basic theory of magnetic flipping

TL;DR: In this paper, the authors show that magnetic reconnection may also occur in three dimensions in the absence of neutral points at so-called quasi-separatrix layers, where there is a steep gradient in field line linkage.

A model for solar polar jets

TL;DR: In this article, a model for the jetting activity that is commonly observed in the Sun's corona, especially in the open-field regions of polar coronal holes, was proposed.

The magnetic topology of solar eruptions

TL;DR: In this paper, the authors present an explanation for the well-known observation that complexity of the solar magnetic field is a necessary ingredient for strong activity such as large eruptive flares.
