Quantum operations on the ring of symmetric functions
Daniel Halpern-Leistner, Andres Fernandez Herrero
We define a version of stable maps into the classifying stack , and develop a corresponding notion of -theoretic Gromov-Witten invariants. In this setting, the e…

Constructible Subcategories and Unbounded Representation Type (with an appendix by Andres Fernandez Herrero)
Kevin Schlegel, Andres Fernandez Herrero
We show that bounded type implies finite type for a constructible subcategory of the module category of a finitely generated algebra over a field, which is a variant of the first B…

Projectivity of the moduli of equidimensional branchvarieties
Daniel Halpern-Leistner, Andres Fernandez Herrero, Trevor Jones +1
We resolve an open problem posed by Alexeev-Knutson on the projectivity of the moduli of branchvarieties in the equidimensional case. As an application, we construct projective mod…
