Periods are integrals of rational differential forms on real
semialgebraic sets. Rational linear combination of Multiple zeta values
are certain well studied subset of periods which form an algebra. These
numbers appear in the beta function of perturbative quantum field theories
but they are not enough to express all of them. Recently there has been a
lot of effort to find a bigger algebra of periods which contain real
numbers coming from QFT's. In this talk I will explain some recent results
in this direction.
