SUMMARY:Braid positivity, taut foliations, and unknot detection
LOCATION:Hill 705

X-EXTRAINFO:Abstract:\nThe L-space conjecture predicts that three seemingly different w
 ays to measure the "size" of a 3-manifold are equivalent. In particular, it
  predicts that a manifold with the "extra" geometric structure of a taut fo
 liation also has "extra" Heegaard Floer homology. In this talk, I'll discus
 s the motivation for this conjecture, and describe some new results which p
 roduce taut foliations by leveraging special properties of positive braid k
 nots. Along the way, we will produce some novel obstructions to braid posit
 ivity. I will not assume any background knowledge in Floer or foliation the
 ories; all are welcome!
