Contractible Image.
|

Hi, All:
Let f: X-->Y be an innesential map, i.e., the image f(X) is not continuously
contractible to a point. Does it follow that the induced map on homology is non-trivial (and, does the converse hold, i.e., does any innessential map induce
a trivial ( i.e., zero) map in homology? I imagine any contractible subspace S has trivial homology, and trivial homotopy ; at least Pi_1(S)=0 .... more »

Looking at the Earth's moon again. To test whether or not it is
spinning we must be located in its dead centre.
Absolute - Relative
Centre - Perimeter
Clear - Blurred
Impartial - Biased
Only in the centre of an object can we truly be impartial observers
who can make a clear absolute statement.... more »
