摘要：
A theory of low frequency Alfven eigenmodes [the global Alfven eigenmodes (GAE) and non-conventional global Alfv'en eigenmodes (NGAE)] in stellarators is developed taking into account the plasma compressibility. It is found that the conditions of existence of GAE/NGAE modes in stellarators differ from those in tokamaks and that the geodesic acoustic mode (GAM) may not exist in stellarators. Specific calculations modeling low-frequency Alfven instabilities in a Wendelstein 7-AS are carried out.
