| Research Abstract |
For a Lie group G, I studied on homotopy groups of the function space of self maps of G. I proved that for any natural number n there exists G of which the nilpotency class of the 0-th homotopy group is greater than n. When G is SU(3) or Sp(2), I and coauthers determined the n-th homotopy group of the function space for 0<n<12. I calculated a quotient group of the group of homotopy classes of self homotopy equivalences of SO(4).
