Some quenched and annealed limit theorems for superprocesses in random environments
Let be a superprocess in a random environment described by a Gaussian noise white in time and colored in space with correlation kernel . When , under the condition that the correlation function is bounded above by some appropriate function , we present the quenched and annealed Strong Law of Large Numbers and the Central Limit Theorems regarding the weighted occupation measure as .
