DESCRIPTION:Title: <a href="https://researchseminars.org/talk/FOTR/61/">Ex
 tremal Surfaces in Positive Characteristic</a>\nby Janet Page (North Dakot
 a State Unviersity) as part of Fellowship of the Ring\n\n\nAbstract\nWhat 
 is the most singular possible point on any variety in positive characteris
 tic?  In recent joint work with Zhibek Kadyrsizova\, Jennifer Kenkel\, Jyo
 ti Singh\, Karen Smith\, Adela Vraciu\, and Emily Witt\, we gave a precise
  answer to this question for cone points on hypersurfaces using a measure 
 of singularity called the F-pure threshold\, and we called these “most s
 ingular” hypersurfaces extremal hypersurfaces.  In this talk\, I’ll fo
 cus on the special case of extremal surfaces and discuss some of their oth
 er surprising properties.  This talk is based on joint work with Anna Bros
 owsky\, Tim Ryan\, and Karen Smith.\n
