- Black-Scholes pricing model has no analytical formula of American put options,thus it cannot get accurate solution.
- This paper presents the accurate solution for the interference of two coherent point sources, which is a family of hyperboloid.
- The simulation results show that the global convergent G-N method can approach a much accurate solution with fewer iteration step.
- It is suggested that considering other data comprehensively at time of interpretation to eliminate subjective forejudge to reach accurate solution.
- A new integrable condition in a kind of special Abel equation is given in this paper. We can realize the special Abel equation integrability and accurate solution by computer.
