Abstract:
As a basic tool of quantum field theory, Feynman integral still plays a crucial role in physics in this 21st century. With the new developments in unitarity analysis, transcendental functions, algebraic structions and differential equations, a lot of complicated Feynman integrals can be evaluated analytically nowadays. These new integral results are of great importance for high energy phenomenology, SYM/Supergravity. In this talk, I give a modern overview of Feynman integrals, and wish that theorists working in other directions may find the mathematical ideals therein useful.
