Query: A fast linearized finite difference method for the nonlinear multi-term
  time-fractional wave equation   In this paper, we study a fast and linearized finite difference method to
solve the nonlinear time-fractional wave equation with multi fractional orders.
We first propose a discretization to the multi-term Caputo derivative based on
the recently established fast L2-1{\sigma} formula and a weighted approach.
Then we apply the discretization to construct a fully fast linearized discrete
scheme for the nonlinear problem under consideration. The nonlinear term, which
just fulfills the Lipschitz condition, will be evaluated on the previous time
level. Therefore only linear systems are needed to be solved for obtaining
numerical solutions. The proposed scheme is shown to have second-order
unconditional convergence with respect to the discrete H1-norm. Numerical
examples are provided to justify the efficiency.
