    "abstract": "In magnetic configurations with two or three q=1 (with q being the safety\nfactor) resonant surfaces in a tokamak plasma, resistive magnetohydrodynamic\nmodes with poloidal mode numbers m much larger than 1 are found to be linearly\nunstable. It is found that these high-m double or triple tearing modes\nsignificantly enhance through nonlinear interactions, the growth of the m=1\nmode. This may account for the sudden onset of the internal resistive kink,\ni.e., the fast sawtooth trigger. Based on the subsequent reconnection dynamics\nthat can proceed without formation of the m=1 islands, it is proposed that\nhigh-m triple tearing modes are a possible mechanism for precursor-free partial\ncollapses during sawtooth oscillations.",
