Description

The general problem of instability of magnetic neutral sheets in the presence of velocity shear is considered. Both resistivity and viscosity are included in the treatment. It is shown that velocity shear and/or viscosity introduce different orderings with respect to resistive tearing modes and that the classical tearing modes represent a singular case. Possible orderings for growth rates are discussed and a specific example containing the effect of velocity shear is treated in detail. (author)
