- I would like to know if there are results for the homotopy group for
- the following class of mappings:
-
- The map of the cartesian product of a two sphere and a three sphere
- (S2xS3) into the unitary groups U(N).
-
- I know that the 5th homotopy group of U(N) is the set of integers, Z,
- for N > 2, but I do not know how to find the results (if they exist)
- for maps which are not just spheres.
-
- An integral which I believe is a representative of this homotopy
- group arises in a physics problem I am thinking about, and if there
- are general results, I would appreciate knowing them.
-
- Please send replies by email to trahern@fremont.ssc.gov (or to the net).
