DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OLS/209/">A 
 Timeline of Lattice Embeddings into the Turing Degrees</a>\nby José Jerem
 ías Valenzuela Morales (George Washington University) as part of Online l
 ogic seminar\n\n\nAbstract\nThe Turing degrees form a rich upper semilatti
 ce. As such\, a natural way to explore their structure is by studying whic
 h types of semilattices can be embedded into them. From Kleene-Post's embe
 ddability result for finite upper semilattices\, to Lerman's embeddability
  criterion and Montalbán's work on jump upper semilattices\, this exposit
 ory talk will survey several classic embedding results with a focus on the
 ir techniques and machinery.\n
