2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/59423We describe some recent development on the theory of formal Frobenius manifolds via a construction from differential Gerstenhaber-Batalin-Vilkovisk (DGBV) algebras and formulate a version of mirror symmetry conjecture: the extended deformation problems of the complex structure and the Poisson structure are described by two DGBV algebras; mirror symmetry is interpreted in term of the invariance of the formal Frobenius manifold structures under quasi-isomorphism.11 pages, to appear in Proceedings of ICCM98Differential GeometryAlgebraic Topologytext
