摘要：
The energy and action for skyrmions in two-dimensional electron gas with nonlocal exchange have been calculated. The energy of positively charged skyrmions is considerably lower than the energy of negatively charged skyrmions and does not contain an exchange contribution. The action has been calculated taking into account collective skyrmion null modes.
