    Abstract. The aim of this chapter is to introduce the fundamentals of post-Hartree-Fock (post-HF) methods to nonexperts by providing the principles and the mathematical background of the most widely applied wave function-based quantum chemical theories: configuration interaction theory, many-body perturbation theory, and coupled-cluster theory. PHYS Mathematical Methods of Theoretical Physics (Dr. Harald W. Griesshammer) in combination with PHYS Computational Physics I, Math. Methd's-segment (Dr. Harald W. Griesshammer) Lectures Mathematical Methods: Tuesday, Thursday to in Staughton All lectures are minutes, equivalent to 4 credit hours. The old theory becomes an approximation to the new theory. Some problems in physics are too complex to solve by direct analysis, or progress could be limited by available analytical tools. Thus, even when the exact representation is known, an approximation may yield a sufficiently accurate solution while reducing the complexity of the problem.

Let us consider two dimensional problems, where the power of complex analysis can be seen quite directly. If a function f(x,y)=u(x,y)+ i v(x,y) is differentiable at z. In mathematics, approximation theory is concerned with how functions can best be approximated with simpler functions, and with quantitatively characterizing the errors introduced thereby.

Note that what is meant by best and simpler will depend on the application. A closely related topic is the approximation of functions by generalized Fourier series, that is, approximations based.
