"I would like it to be possible to solve digitally, in a user-friendly way, the problems modeled by partial differential equations (PDEs) from physics, engineering, computing graphics and recently from the finance-banking sector. This problem is therefore at the interface between applied mathematics, numerical analysis, computer science and the relevant applications (fluid mechanics, electromagnetism, quantum mechanics and stock options in finance)." |
