Exploration of Continuous Compound Interest in Complex Numbers

Abstract

In the past, the interest rate functions, including continuous compound interest rate functions, were solved in real numbers. Scholars believe that interest rate functions in the other numeral system are meaningless for most financial markets. In the development of the times, financial events such as negative interest rates continue to break out, and more financial black swan events can happen beyond the current financial investment theory; The exploration of the formula of continuous compound interest rate from the perspective of complex numbers will help us find more features of the law of the financial market.
