DESCRIPTION:In this talk I present a joint work with Marcello 
 Bernardara where we show that a standard conic bun
 dle on a rational minimal surface is rational if a
 nd only if its derived category admits a semiothog
 onal decomposition via derived categories of smoot
 h projective curves and exceptional objects. In pa
 rticular\, even if the surface is not minimal\, su
 ch a decomposition allows to reconstruct the inter
 mediate Jacobian as the direct sum of the Jacobian
  of those curves.\n
