Comment (by novoselt):
Your use of the term "trivial cone" is confusing - after reading the very
first example I thought "Surely any transformation is Lyapunov-like since
there is no conditions to worry about!", yet their basis was empty. To me
"trivial cone" means "consisting of the origin" and there are multiple
trivial cones - one for each lattice, which of course should be
distinguished from the point of view of toric geometry. Sometimes, looking
at the doc of discrete complementarity set, you seem to mean the same
things, while in other places you mean "the only cone in the 0-dimensional
space" where indeed the basis of all transformations is empty as there are
no transformations at all (or I guess there is one which is both zero and
identity or however one wants to interpret it). I would prefer sticking to
"just the origin" and updating docs to include a positive-dimensional
ambient space as well.
