Query: Statistical instability for contracting Lorenz flows   We consider one parameter families of vector fields introduced by Rovella,
obtained through modifying the eigenvalues of the geometric Lorenz attractor,
replacing the expanding condition on the eigenvalues of the singularity by a
contracting one. We show that there is no statistical stability within the set
of parameters for which there is a physical measure supported on the attractor.
This is achieved obtaining a similar conclusion at the level of the
corresponding one-dimensional contracting Lorenz maps.
