Abstract:
We give many examples of applying Bogoliubov's forest formula to iterative
solutions of various nonlinear equations. The same formula describes
an extremely wide class of objects, from an ordinary quadratic equation to
renormalization in quantum field theory.
Keywords:
quantum field theory, renormalization, nonlinear algebra.
