Backward Uniqueness for Coupled Ultraparabolic Operators and an Application to Jerk-Driven Control Models

Xiao-Dong Cao, Chao-Jiang Xu, Yan Xu

We prove backward uniqueness for a class of ultraparabolic operators with coupled linear drift. The main difficulty is that the Fourier transform in the degenerate variables turns…
