DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MITNT/130/">
 Gluing triples</a>\nby Piotr Achinger (IMPAN Warsaw and Kyiv School of Eco
 nomics) as part of MIT number theory seminar\n\nLecture held in Room 2-449
  in the Simons Building (building 2).\n\nAbstract\nFor a scheme over $\\ma
 thbb{Q}_p$\, we wish to describe the ways of extending over $\\mathbb{Z}_p
 $ using formal and rigid geometry. Our main theorem does this over arbitra
 ry (excellent) base provided we replace schemes with separated algebraic s
 paces. This result can be seen as a version of Beauville–Laszlo/Artin gl
 uing of coherent sheaves\, but for spaces\, and turns out to be closely re
 lated to Artin's contraction theorem. This is joint work with Alex Youcis.
