Cosmology meets cohomology
Published 2024-03-01“…Moreover, we further develop our geometric understanding of these integrals by describing the associated relative twisted cohomology. Leveraging recent progress in our understanding of relative twisted cohomology in the Feynman integral community, we give an algorithm to predict the basis size and simplify the computation of the differential equations satisfied by FRW correlators.…”

Heterotic quantum cohomology
Published 2022-11-01“…We conjecture that one could better study the moduli space of heterotic theories by studying the corresponding cohomology, a natural counterpart to studying the ∂ ¯ $$ \overline{\partial} $$ -cohomology groups relevant to moduli of Calabi-Yau manifolds.…”
