SUMMARY:Cluster gluings and open-string Schubert calculus
LOCATION:H705
DESCRIPTION:<pre><span size="4" style="font-size: large;">When is a gluing of affine sc
 hemes affine? I will state a complete butconjectural answer when the pieces
  are tori, and the gluing maps arecluster mutations in the sense of Fomin-Z
 elevinsky. The combinatoricsof Demazure weaves allows to prove the conjectu
 re in interestingcases, notably those in which there are finitely many tori
 , as well asthe simplest ones with infinitely many. This has applications t
 oopen-string Schubert calculus, i.e. computations of the Fukayacategory of 
 G/P. Joint work with M. Gorsky, J. Simental, D. Speyer.</span></pre>
