文摘In this paper,the existence theorem for a quasi solution of an inverse fractional stochastic parabolic equation driven by multiplicative noise in the form cD_(t)^(a)u-div(g(x,▽u))=f(x,u)+σ(x,u)w(t)is given.In this equation,the fractional derivative is considered in the Caputo sense.Also,the random function g is unknown and should be determined.To identify the unknown coefficient,the minimization and stochastic variational formulation methods in a fractional stochastic Sobolev space are used.Indeed,we obtain a stability estimation and then prove the continuity of the minimization functional using obtained stability estimation.These results show the existence of the quasi solution for the mentioned problem.
