A remark on monoidal structure and homological mirror symmetry

Abstract

For a symplectic geometry XX, suppose the (derived) Fukaya category Fuk(X)\mathrm{Fuk}(X) of XX is equipped with a monoidal structure. Then its Balmer spectrum recovers a mirror YY of XX if there exists homological mirror symmetry Fuk(X)Dbcoh(Y)\mathrm{Fuk}(X)\cong D^b\mathrm{coh}(Y) and the monoidal structure is the mirror of the standard one of Dbcoh(Y)D^b\mathrm{coh}(Y). In this short note, we fill one gap of this story in the literature: we show that the monoidal structure determines the homological mirror functor Fuk(X)Dbcoh(Y)\mathrm{Fuk}(X)\to D^b\mathrm{coh}(Y).
