Necessary and sufficient condition for the comparison theorem of multidimensional anticipated backward stochastic differential equations

Anticipated backward stochastic differential equations, studied the first time in 2007, are equations of the following type: {tabular}{rlll} $-dY_t$ &=& $f(t, Y_t, Z_t, Y_{t+δ(t)}, Z_{t+ζ(t)})dt-Z_tdB_t,$ & $t\in[0, T];$ $Y_t$ &=& $ξ_t,$ & $t\in[T, T+K];$ $Z_t$ &=& $η_t,$ & $t\in[T, T+K].$ In this paper, we give a necessary and sufficient condition under which the comparison theorem holds for multidimensional anticipated backward stochastic differential equations with generators independent of the anticipated term of $Z$.
