چکیده
In this paper, we investigate and analyze numerical solutions for the Volterra integrodifferential equations with tempered multi-term kernels. Firstly, derive some regularity estimates of exact solution. Then a temporal-discrete scheme is established by employing Crank-Nicolson technique product integration (PI) rule discretizations time derivative tempered-type fractional integral terms, respectively, from which, nonuniform meshes are applied to overcome singular behavior solution at $$t=0$$ . Based on deduced conditions, prove that proposed unconditionally stable possesses accurately temporal second-order convergence in $$L_2$$ -norm. Numerical examples confirm effectiveness method.

where q : I → R, pi : I → R, and ki : D → R (i = 0,1) (with D := {(t,s) : 0 ≤ s ≤ t ≤ T}) are given functions and are assumed to be (at least) continuous in the respective domains. For more details of these equations, many other interesting methods for the approximated solution and stability procedures are available in earlier literatures [1, 3, 4, 5, 6, 7, 8, 11]. The above equation is usually...
