    <div align="left"><b><b><font color="#ff0000">Abstract:</font></b></b><font
        color="#ff0000"><font color="#000000"> Mirror symmetry is one of
          the most striking developments in modern mathematics whose
          scope extends to very different fields of pure mathematics. It
          predicts a broad correspondence between two subfields of
          geometry - symplectic geometry and algebraic geometry.
          Homological mirror symmetry uses the language of triangulated
          categories to give a mathematically precise meaning to this
          correspondence. Since its announcement, by Kontsevich in ICM
          (1994), it has attracted huge attention and over the years
          several important cases of it have been established. Despite
          significant progress, many central problems in the field
          remain open. After reviewing the general features, I will
          survey some of my recent results on mirror symmetry (with
          thanks to collaborators T. Perutz, A. Polishchuk, K. Ueda, D.
          Treumann).<br>
