講演者：Professor Sigmundur Gudmundsson（Lund University, SWEDEN）
タイトル：Harmonic morphisms, complex analysis and how to generalize it. 
(1st lecture)
日時：２０１０年２月１８日（木）１０：４０〜１２：１０
場所：数学講究室（３０４０）
アブストラクト：
     It is a well-known result in classical complex analysis that every 
holomorphic or anti-holomorphic function is harmonic and conformal.
It is easy to see that they also pull back harmonic real-valued 
functions to harmonic functions.  This last property actually 
characterizes
the holomorphic and anti-holomorphic functions in the complex plane.
   Harmonic morphisms are maps (M,g) -> (N,h) between Riemannian 
manifolds which pull back harmonic functions to harmonic functions.
They have many properties similar to those of holomorphic functions 
which they generalize.
   We will give a general introduction to the theory of harmonic 
morphisms

講演者：Professor Sigmundur Gudmundsson（Lund University, SWEDEN）
タイトル：Harmonic morphisms from Lie groups and symmetric spaces (2nd 
lecture)
日時：２０１０年２月１８日（木）１６：２０〜１７：５０
場所：数学講究室（３０４０）
アブストラクト：
    We will discuss the existence problem for harmonic morphisms between 
Riemannian manifolds.  In particular we shall focus our attention on
recent results on complex-valued harmonic morphisms from Lie groups and 
symmetric space.
