| Quantum mechanics is the basic theory on studying microscopic particles, it con-stitutes the two pillars of physics with relativty. In the financial markets, the evolution process of risky assets whether to comply with such rules of quantum statistics? And then we issue financial problems from the perspective of quantum mechanics, Attracted more and more mathematics and physicists who directly involve in the financial markets. In this paper, Mainly from the perspective of quantum mechanics, we establish a financial market model, Using Markowitz portfolio selection theory we discuss the single financial market assets on optimal portfolio problem. Using dynamical programming principle, We describe briefly the quantum discrete time financial market asset investment strategy optimal solution. |
