Abstract
The energy and action for skyrmions in two-dimensional electron gas with no nlocal exchange have been calculated. The energy of positively charged skyr mions is considerably lower than the energy of negatively charged skyrmions and does not contain an exchange contribution. The action has been calcula ted taking into account collective skyrmion null modes. (C) 1999 American I nstitute of Physics. [S1063-7761(99)02302-1].
