- 摘要:
-
对右侧α(0<α<1)阶Caputo分数阶导数在t=tk处进行了差分离散,分别在区间[tj-1,tj](j∈[k+1,N-1])上用L2插值,在区间[tN-1,tN]上用L1插值,构造了L2-1差分格式,给出了相关的系数性质,并证明了其收敛阶为O(Δt3-α)。
- Abstract:
-
The difference of the right side of the Caputo fractional derivation at t=tk was discretized by using L2 interpolation on interval[tj-1,tj](j∈[k+1,N-1]) and L1 interpolation on interval[tN-1,tN]respectively.The L2-1 difference scheme was constructed,and the properties of the related coefficient were given,and it was proved that the convergence order was O(Δt3-α).
