This paper investigates a Caputo time fractional advection-diffusion equation with nonhomogeneous integral-type boundary conditions and proves the existence and uniqueness of the solution using the a priori estimate method. The approximate solution is established by a combination of the finite difference method and numerical integration, and numerical tests are conducted to demonstrate the usefulness of the obtained results.
In this paper, we are interested in the study of a Caputo time fractional advection-diffusion equation with nonhomogeneous boundary conditions of integral types integral(0) v(x, t)dx and integral(0) x(n)v (x, t)dx.. The existence and uniqueness of the given problem's solution is proved using the method of the energy inequalities known as the a priori estimate method relying on the range density of the operator generated by the considered problem. The approximate solution for this problem with these new kinds of boundary conditions is established by using a combination of the finite difference method and the numerical integration. Finally, we give some numerical tests to illustrate the usefulness of the obtained results.
