Abstract

We introduce LL_{\infty}-Kuranishi spaces by associating, to each chart, L[1]L_{\infty}[1]-algebras defined on open neighborhoods of points in the zero locus of the Kuranishi section. We show that these objects collectively form a category into which the category of smooth manifolds naturally embeds. Some notions in \cite{FOOO1} are modified to achieve the desired categorical structures; for instance, the tangent bundle condition for chart embeddings is replaced by a quasi-isomorphism condition for the L[1]L_{\infty}[1]-structures.
