<p>Hi,</p> <p>the face poset of a complete simplicial fan is a simplicial sphere. It is not shellable in general, but Kleinschmidt, Smilansky and Onn shown that it is always partitionnable. Constructibility is a notion slightly weaker than shellability. Is it known whether a (simplicial complete) fan is constructible or not? </p> <p>Thanks in advance.</p>
