Chair of Mathematics

The Chair of Mathematics is responsible for the teaching of Mathematics at the University of St. Gallen and conducts research in the area of quantitative methods for economics and finance.

Economic theory is often presented in terms of mathematical models. Mathematical methods such as differential and integral calculus, linear algebra, differential equations, convex optimization, probability theory, control theory, stochastic calculus, stochastic control, etc., are widely applied in economics and finance and contribute to the development of a theoretical foundation for advancing modern economics and finance.

Hence, mathematics proves beneficial to economists in two ways: it allows them to formulate a rigorous framework for understanding the links between economic variables and helps to derive testable implications.
