Because of convergence problems with Floer theoretic constructions, it is difficult to make this procedure completely rigorous. Kontsevich and Soibelman thus proposed to consider the mirror as a rigid analytic space, defined over the field C((t)), equipped with the non-archimedean t-adic valuation, or more generally over the Novikov field. This is natural because the Floer theory of a symplectic manifold is defined over the Novikov field.
After explaining this background, I will give some indication of the tools that enter in the proof of homological mirror symmetry in the simplest class of examples which arise from these considerations, namely Lagrangian torus fibrations without singularities.
