Abstract

We review progress on a heterotic analogue of quantum coho-
mology, known as ‘quantum sheaf cohomology’. Whereas ordinary quantum
cohomology is computed by intersection theory on a moduli space of curves,
quantum sheaf cohomology is computed via sheaf cohomology on a moduli
space of curves.
