TY - JOUR ID - TI - On Pre-Lie Magnus Expansion AU - Mahdi Jasim Hasan Al-Kaabi PY - 2019 VL - 00 IS - 2 SP - 101 EP - 112 JO - Al-Nahrain Journal of Science مجلة النهرين للعلوم SN - 26635453 26635461 AB - In this paper, the classical and pre-Lie Magnus expansions have been studied, discussing how one can find a recursion for the pre-Lie case which already incorporates the pre-Lie identity. A combinatorial vision of a numerical method proposed by S. Blanes, F. Casas, and J. Ros in [4], has been given on a writing of the classical Magnus expansion in a free Lie algebra, using a pre-Lie structure.
