DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NYC-NCG/194/
 ">Noncommutative geometry in effective field theory and large N phenomena<
 /a>\nby Alastair Hamilton (Texas Tech University) as part of Noncommutativ
 e geometry in NYC\n\n\nAbstract\nIn this talk I will discuss the notion of
  an effective field theory\, as formally introduced by Costello\, and its 
 manifestation in the framework of noncommutative geometry introduced by Ko
 ntsevich. Noncommutative geometry arises within this context from replacin
 g ordinary Feynman diagrams with diagrams of interacting open strings\, an
 d I will explain how the large N phenomena first discovered by ‘t Hooft 
 arises in this framework. Here a connection can be made between these open
  string type theories that arise in noncommutative geometry and large N ga
 uge theories using the Loday-Quillen-Tsygan theorem from algebraic K-theor
 y. If time permits\, I may discuss the treatment of the Batalin-Vilkovisky
  formalism within this context and the connection with moduli spaces of Ri
 emann surfaces.\n
