DESCRIPTION:Dual span bundles have been constructed and used o
n many different purposes in algebraic geometry.\n
\nThe stability of these bundles has been proven i
n many cases and with different applications\, fro
m normal generation to the studying of the Picard
sheaf\, from the investigation on generalized thet
a-divisors\, to that of coherent systems and Brill
-Noether loci.\n\nWe discuss about a work in progr
ess with Lidia Stoppino\, relating the stability o
f these bundles to the linear stability of linear
systems on curves as defined by Mumford\, providin
g some questions\, some examples\, few answers\, a
nd illustrating some connection with Butler's conj
ecture on stability of dual span bundles.\n\n
