    Hi I’m trying to figure out some basic things.
    Maybe you have some entries in your blog about them.

    I’m trying to figure out Hom(O(n),O(m))
    for O(n) being the usual line bundle on the projective space over a field.
    Actually I would like to know
    Ext^i(O(n),O(m)). I think I understand the maps
    of the corresponding graded modules.

    Anyway do you have any blog entries on those?
    Otherwise I would make that a request.

    Thanks,
    Don
