摘要: In this paper, we prove Talagrand's $ T_2 $ transportation cost-information inequality for the law of stochastic heat equation driven by Gaussian noise, which is fractional for a time variable with the Hurst index $H\in\left(\frac12,\,1\right)$, and is correlated for the spatial variable. The Girsanov theorem for fractional-colored Gaussian noise plays an important role in the proof.
