We investigate the transport equation . Our result improves the classical criteria of uniqueness of weak solutions in the case of irregular coefficients: b ∈ BV, . To obtain our result we use a procedure similar to DiPerna and Lions’s one developed for Sobolev vector fields. We apply renormalization theory for BV vector fields and logarithmic type inequalities to obtain energy estimates.
