The geometric string structure conjecture for Chern–Simons enhancements
Let $K$ be a Lie group and let $P_K:M\to\mathrm{B}K$ classify a principal $K$ -bundle. Let $\mathrm{B}^2\mathrm{U}(1)\to\mathrm{String}(K)\to K$ be the string extension, enhanced to…

The differential string trivialization conjecture for Witten Pfaffian lines
Let $(M_{8\ell+2},g_M^{\mathrm{spin}})$ be a closed differential spin manifold, and let $g_M^{\mathrm{string}}$ be a lift of its spin structure to a differential string structure.…
