概要Computer algebra systems such as Maple and Mathematica play an every increasingly important role in mathematics teaching and research across a broad range of disciplines. In this series of lectures, I shall discuss the use of Maple in the area of differential geometry and its applications to differential equations, the calculus of variations and mathematical physics. The format for each lecture will be the same - we shall review the relevant mathematical concepts and then illustrate these concepts using the Differential Geometry software package. Some details of various algorithms will be presented and on-going developments and open problems will be discussed. The software demonstrations will be made available to all conference participants. (Participants may wish to bring their laptops (with Maple - Release 11 or higher) but this is not required.)
