This is a new topic at present. With more and more Nobel Prize in Economics awarded to econometric researchers, scholars pay more and more attention to the application of mathematics in financial research. The biggest feature of this subject is to use mathematical models to explain and study financial problems.
The process of modernization and precision of any subject will inevitably lead to the use of mathematics as its own language. The modernization of modern finance independent of economics is reflected in the quantification of finance. The quantification of financial science means that the research mode of financial theory tends to be mathematical (referring to the deduction of mathematics), the quantification of applied research (referring to the establishment of corresponding mathematical models) and the extensive use of computer technology to solve numerical problems of models, thus contributing to the birth and development of financial mathematics. Financial mathematics is a new interdisciplinary subject between finance and mathematics (especially optimization theory, advanced probability theory, stochastic calculus, partial differential equations, etc.). ), also known as mathematical finance.
