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.
