SUMMARY:Some observations on Tannaka duality - Ignacio Lopez-Franco\, Univ
 ersity of Coimbra

DESCRIPTION:Tannaka duality studies the relationship between certain algeb
 raic\nstructures (usually coalgebras\, perhaps with extra structure) and\n
 their categories of representations. One of the main problems\nis to chara
 cterise those categories that are categories of finite\nrepresentations of
  a coalgebra.\n\nI'll discuss different frameworks to study Tannaka dualit
 y and explain\nwhy I think we are yet to found the right one.
