  • Abstract

A spatial compact difference scheme for a class of fourth-order temporal multi-term fractional wave equations is developed. The original problem is reduced to a lower order system and the corresponding time fractional derivatives are approximated by the L1-formula. The unconditional stability and convergence of the difference scheme are proved by the energy method. Numerical experiments support theoretical results.

  • Keywords

Compact difference scheme, multi-term fractional derivatives, spatial fourth-order derivative, stability, convergence.
