Fluctuations for a conservative interface model on a wall
Equilibrium fluctuations Interface model Stochastic partial differential equations hard wall
2009/6/12
We consider an effective interface model on a hard wall in(1+1)dimensions,with conservation of the area between the interface and the wall.We prove that the equilibrium fluctuations of the height vari...
