Introduction and results Let Y be a projective manifold. Denote by Y k,β the moduli stack of rational stable maps of class β∈ H 2(Y,Z) with k-markings [FP] and [Y TīmeklisAbstract: We study tight projective 2-designs in three different settings. In the complex setting, Zauner's conjecture predicts the existence of a tight projective 2-design in every dimension. Pandey, Paulsen, Prakash, and Rahaman recently proposed an approach to make quantitative progress on this conjecture in terms of the entanglement ...

It turns out that the coefficients describing the decompositions of Betti tables into pure diagrams in Boij-Söderberg theory are much more explicit than the Betti tables ...

Tīmeklisn are pure-projective, then Mis pure-projective. In other words, every pure-periodic R-module Mis pure-projective. As a consequence of Theorem 1.3 we get the following … Tīmeklisprojective variety is rationally isomorphic to its numerical Chow ring, so N.†/has rank 4. Similarly, since, by Lemma 3.6 below, the Picard rank of Zis 3, it follows that N.Z/has rank 8. Thus from the above direct sum decomposition we conclude that N.†;C`0/has rank 4. Therefore, to prove the lemma it suffices to show that objects (3-4) give ...
