Abstract
We present analysis of the cross-over behavior of
disordered interacting two-dimensional electron systems in the
parallel magnetic field. Using the so-called cross-over one-loop
renormalization group equations for the resistance and
electron-electron interaction amplitudes we qualitatively explain
experimentally observed transformation of the temperature
dependence of the resistance from a reentrant (nonmonotonic)
behavior in relatively weak fields into an insulating-type
behavior in stronger fields.
