Let $E$ be a holomorphic vector bundle over $\mathbb{P}^n\setminus\begin{Bmatrix}[1,0,0,\cdots,0]\end{Bmatrix}$. Let $D$ be a connection on $E$. Let $\widetilde{E}$ be an extension of $E$. Since $\widetilde{E}$ is reflexive, i.e. double dual of $E$ is isomorphic to itself, then up to isomorphism, $\widetilde{E}$ is unique. My questions are


1)
Is it possible that $\widetilde{E}$ is a vector bundle? 


2) If $\widetilde{E}$ is a vector bundle, does it admit a connection $\widetilde{D}$ which is naturally induced by $D$?


Edit:For the first question, I just proved that $\widetilde{E}$ is a vector bundle if and only if $\widetilde{E}$ is splits. I am wondering if this result was already known. If so, does any one know any reference on this result?



Extension of a holomorphic vector bundle
Presumably, you assume $n\ge 2$.


1) Is it possible that $\tilde E$ is a vector bundle? Yes. Is it always a vector bundle for any $E$? No. Unless, of course, you assume that the connection is flat and holomorphic, then
it extends essentially for topological reasons.


2) Does the connection extends to $\tilde E$ if it is a vector bundle? Assuming the connection is holomorphic, the answer is yes: locally, the connection is given by a bunch of holomorphic functions that extend across codimension two.
