DESCRIPTION:Title: <a href="https://researchseminars.org/talk/operad/11/">
 The operad of framed formal curves and a program of Kontsevich</a>\nby Dmi
 try Vaintrob (University of California\, Berkeley) as part of operad pop-u
 p\n\n\nAbstract\nIt has long been conjectured (originally formalized by Ko
 ntsevich) that the operad of framed little disks can be enriched to an ope
 rad in an appropriate category of motives (in the sense of Grothendieck an
 d Voevodsky). I will explain such a construction\, in a motivic category a
 ssociated to logarithmic schemes (or more generally\, stratified formal sc
 hemes) and explain how (via ideas of Kontsevich\, Tamarkin\, Beilinson and
  others)\, this construction leads to a systematic resolution of several f
 ormality and deformation theoretic results\, including the Deligne formali
 ty conjecture and deformation-quantization previously proven via more tran
 scendental techniques.\n
