I am trying to up my understanding on Manifolds, Tensors and Forms by reading a book of that title by Paul Renteln.
I have got stuck fairly early on by his use of "exact sequences". Can some one give me a concrete example of a shot exact sequence of the form 0 -> U->V->W->0 where U,V,W are vector spaces 0 is the null vector space and the -> are linear maps not necessarily the same one each time. I do think I understand the ker of U and I am U etc.
I have tried various web pages but they give abstract examples which don't seem to help and I am obviously in a gumption trap!
I trust this is the right place to ask and this is personal study out of interest and in no way a homework assignment!
Regards Andrew
