Abstract
To every simple toric ideal one can associate the strongly robust simplicial complex , which determines the strongly robust property for all ideals that have as their bouquet ideal. We show that for the simple toric ideals of monomial curves in , the strongly robust simplicial complex is either or contains exactly one 0-dimensional face. In the case of monomial curves in , the strongly robust simplicial complex contains one 0-dimensional face if and only if the toric ideal is a complete intersection ideal with exactly two Betti degrees. Finally, we provide a construction to produce infinitely many strongly robust ideals with bouquet ideal the ideal of a monomial curve and show that they are all produced this way.
