Description
We study surprising connections between algebraic topology and string theory amplitudes which underlie Kawai–Lewellen–Tye (KLT) relations. For instance, we show that entries of the inverse KLT kernel can be understood as intersection numbers of certain cycles. In the field-theory limit, combinatorics of these intersections gives rise to the bi-adjoint scalar theory.
