DESCRIPTION:We consider the invariant measure and flow of the Phi4-model o
 n the three-dimensional torus\, which appears in the quantum field theory.
  By virtue of Hairer&#39\;s breakthrough\, such a nonlinear stochastic par
 tial differential equation became solvable and is studied as a hot topic. 
 In the talk\, we apply the paracontrolled calculus and directly construct 
 the global solution and the invariant measure by using the invariant measu
 res of approximation equations and showing the tightness of associated pro
 cesses. This is a joint work with Sergio Albeverio.
