SUMMARY:Real algebra\, random walks\, and information theory
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTOBIAS FRITZ\, PERIMETER INSTITUTE\n\nSimilar to ho
 w commutative algebra studies rings and their ideals\, the\nprotagonists o
 f real algebra are ordered rings. Their interplay\nbetween algebra and geo
 metry is studied in terms of Positivstellen-\nstze\, real analogs of the N
 ullstellensatz\, which go back to Artin's\nsolution of Hilbert's 17th prob
 lem. I will describe some of the state\nof the art in this eld\, and then 
 introduce a new Positivstellensatz\nwhich unies and generalizes several of
  the existing ones.\n
