DESCRIPTION:The theme of this lecture will be the global properties of per
 iod mappings with applications to compactifications of moduli spaces. Give
 n a variation of Hodge structure over a smooth quasi-projective variety B\
 , we will define and discuss properties of maximal and minimal extensions 
 $\\Phi_T$ and $\\Phi_S$ of the corresponding period mapping $\\Phi$. Of pa
 rticular interest will be the fibration over the divisor at infinity of th
 e images of $\\Phi_T$ and $\\Phi_S$ in which the rich geometry of the exte
 nsion date of limiting mixed Hodge structures will be analyzed. The genera
 l theory will then be illustrated for the boundary of the moduli space of 
 one particularly interesting algebraic surface.\n*Joint work with Mark Gre
 en and Colleen Robles
