摘要：

For the non-linear two-dimensional ideal MHD equations we use the known Lie point symmetries and for the case of adiabatic exponent gamma = 2 we give local Lie-Backlund symmetries. We find exact solutions using similarity analysis. Among the calculated similarity solutions describing plasma expansion into vacuum, shock waves and spiral flows with plasma sources.
