Compatibility of logarithmic and ordinary Hochschild functoriality
Compatibility of logarithmic and ordinary Hochschild functoriality
Let and be log smooth pairs, and let be a strong Fourier–Mukai kernel on . Let be the projection and regard the proper pushforward as a Fourier–Mukai kernel. The kernel induces a map on logarithmic Hochschild homology, while induces a map on ordinary Hochschild homology. Compatibility conjecture. The diagram
commutes, where the vertical maps are induced by the counit map from the self-intersection of the diagonal to the self-intersection of the log diagonal. This would relate ordinary and logarithmic Fourier–Mukai actions through the natural comparison maps.
