There is no evidence to the contrary.

Computer evidence suggests the dynamics of these maps is rich and varied.

Some partial evidence to support this conjecture is discussed in [3].

We offer numerical evidence to support a conjecture that there exist infinitely many primes of this type.

This is true even if $H^{2}(B)=0$, as evidenced by the existence of manifolds whose affine base is a Klein bottle.
