In this paper we prove the existence of approximate controls for certain classes of parabolic problems with non-smooth coefficients and discuss as examples the problem of approximate controllability for the heat flow in heterogeneous media such as, periodic composites, perforated domains or periodic microstructures separated by rough interfaces.

具有非光滑系数的抛物线问题的近似可控性

在本文中，我们证明了某些类型的具有非光滑系数的抛物线问题的近似控制的存在，并举例讨论了非均质介质（如周期复合材料，多孔区域或周期微结构）中热流的近似可控性问题。粗糙的界面。
