DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SGFM/5/">Flu
 xes\, Twisted Tori\, Monodromy and $U(1)$ supermembranes</a>\nby M. Pilar 
 García del Moral (Universidad de Antofagasta) as part of Seminario de Geo
 metría y Física - Matemática UCN-USP\n\n\nAbstract\nIn this talk I will
  discuss about recent advances in the characterization of Supermembrane Th
 eory with constant fluxes. I will show that the $D=11$ Supermembrane theor
 y (M2-brane) compactified on a $M_9\\times T^2$ target space\, with consta
 nt fluxes $C_\\pm$ naturally incorporates the geometrical structure of a t
 wisted torus. Its global formulation corresponds to a twisted torus bundle
  fibered over the world volume of the supermembrane. This structure allows
  to understand better its effective limit described by the  Type II Gauged
  supergravities. The spectrum of the theory is purely discrete\, with fini
 te multiplicity. The theory is invariant under symplectomorphisms connecte
 d and non-connected to the identity\, a result relevant to guarantee the U
 -dual invariance of the theory. The Hamiltonian of the theory exhibits int
 eresting new $U(1)$ gauge and global symmetries on the world volume induce
 d by the symplectomorphism transformations. I will discuss also its  super
 symmetric algebra. The zero modes decouple from the nonzero ones. The nonz
 ero mode algebra corresponds to a massive superalgebra that preserves eith
 er $1/2$ or $1/4$ of the original supersymmetry depending on the state con
 sidered.\n\nThis talk is based on:\n\n1.Fluxes\, Twisted tori\, Monodromy
