We consider the following stochastic heat equation:`\partial_t u_t(x)=\partial_{xx}u_t(x)+\sigma(u_t(x))\dot{W}(t,x)`,`x\in(-\infty,\infty)` or `x\in[-1,1]` with certain boundary conditions subject to initial data `u_0(x)`. We will discuss how initial data and the noise term effect the behaviors of the solution. This is based on several different papers.
