Query: Dynamical instability of the electric transport in strongly fluctuating
  superconductors   Theory of the influence of the thermal fluctuations on the electric transport
beyond linear response in superconductors is developed within the framework of
the time dependent Ginzburg - Landau approach. The I - V curve is calculated
using the dynamical self - consistent gaussian approximation. Under certain
conditions it exhibits a reentrant behaviour acquiring an S - shape form. The
unstable region below a critical temperature $T^{\ast }$ is determined for
arbitrary dimensionality ($D=1,2,3$) of the thermal fluctuations. The results
are applied to analyse the transport data on nanowires and several classes of
2D superconductors: metallic thin films, layered and atomically thick novel
materials.
