- Pseudospectral differentiation operator
- The Hamiltonian of the system is the Driac operator which as a matrix differential operator is not semibounded from below.
- Soble filter processing result, the visual impression that the only differential operator out the details mentioned in the outline of a number of relatively obvious.
- In this paper,a optimal finite difference scheme based on the optimal FIR method is discussed,with which the ideal differential operator is approximated in the frequency or spetial domain.
- The theorem of the variational problems of the complete functional is proposed and proved.The complete Euler equation set is obtained through the introduction of the partial differential operator.
- partial differential operator on manifold
