  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>The full Maxwell
    equations in the unbounded three-dimensional space coupled to the Landau–Lifshitz–Gilbert
    equation serve as a well-tested model for ferromagnetic materials.\r\nWe propose
    a weak formulation of the coupled system based on the boundary integral formulation
    of the exterior Maxwell equations.\r\nWe show existence and partial uniqueness
    of a weak solution and propose a new numerical algorithm based on finite elements
    and boundary elements as spatial discretization with backward Euler and convolution
    quadrature for the time domain.\r\nThis is the first numerical algorithm which
    is able to deal with the coupled system of Landau–Lifshitz–Gilbert equation and
    full Maxwell’s equations without any simplifications like quasi-static approximations
    (e.g. eddy current model) and without restrictions on the shape of the domain
    (e.g. convexity).\r\nWe show well-posedness and convergence of the numerical algorithm
    under minimal assumptions on the regularity of the solution.\r\nThis is particularly
    important as there are few regularity results available and one generally expects
    the solution to be non-smooth.\r\nNumerical experiments illustrate and expand
    on the theoretical results.</jats:p>"
