Abstract
It is proved that (set-theoretic) interval multiplication is inverse inclusion isotone. The centered outward interval multiplication (co-multiplication) is studied in some detail with respect to inclusion isotonicity. To a system of linear interval algebraic equations we associate a system involving co-multiplication. The latter reduces to two real linear systems of the same size for the midpoint-radius coordinates of the unknown intervals. We show that under certain assumptions these real linear systems produce an inner inclusion for the tolerance solution of the original interval system.
