The first contribution of this EMS volume on complex algebraic geometry touchres upon many ofthe central problems in this vast and very active area of current research. While it is much too short to
　　provide complete coverage of this subject， it provides a succinct summary of the areas it covers， while providing in-depth coverage ofcertain very important fields.
　　The second part provides a l，rief and lucid introduction to the recent work on the interactions between the classical area of the geometry ofcomplex algebraic curves and their Jacobian varieties， and Partial differential Equations ofmathematical physics. The paper discusses the work of Mumford， Novikov， Krichever， and Shiots， and would be an excellent companion to the older classics on the subject.
