We construct projective toric surfaces whose blow-up at a general point has a non-
polyhedral pseudo-effective cone. As a consequence, we prove that the pseudo-effective …

Representations of certain vertex algebras, here called of CohFT-type, can be used to
construct vector bundles of coinvariants and conformal blocks on moduli spaces of stable …

The aim of this paper is to generalize the notion of conformal blocks to the situation in which
the Lie algebra they are attached to is replaced with a sheaf of Lie algebras depending on …

We introduce and study the problem of finding necessary and sufficient conditions under
which a conformal blocks divisor on M¯ 0, n M _ 0, n is nonzero, solving the problem …

Given a simple, simply connected, complex algebraic group G, a flat projective connection
on the bundle of non-abelian theta functions on the moduli space of semistable parabolic G …

Classical invariants for representations of one Lie group can often be related to invariants of
some other Lie group. Physics suggests that the right objects to consider for these questions …

Basepoint free cycles on the moduli space of stable-pointed rational curves, defined using
Gromov–Witten invariants of smooth projective homogeneous spaces are introduced and …

We consider a conjecture that identifies two types of base point free divisors on M¯ 0, n. The
first arises from Gromov-Witten theory of a Grassmannian. The second comes from first …
