In mathematics and physics, the Magnus expansion, named after Wilhelm Magnus (1907–1990), provides an exponential representation of the solution of a first order linear homogeneous differential equation for a linear operator. In particular it furnishes the fundamental matrix of a system of linear ordinary differential equations of order with varying coefficients. The exponent is built up as an infinite series whose terms involve multiple integrals and nested commutators.
