Why do you mention the fact that every extension of line bundles on $\mathbb P^2$ splits? In any case, if $E$ fits in a short exact sequence of vector bundles, say with left and right terms respectively $\mathcal O(a)$ and $\mathcal O(b)$, then its Chern classes are given respectively by $a+b$ and $ab$, and one may certainly choose $k$ and $m$ to be not of that form, isn't it? | |
