Query: Global convergence in systems of differential equations arising from
  chemical reaction networks   It is shown that certain classes of differential equations arising from the
modelling of chemical reaction networks have the following property: the state
space is foliated by invariant subspaces each of which contains a unique
equilibrium which, in turn, attracts all initial conditions on the associated
subspace.
