   Sažetak:

We present a membrane sigma model constructed from the Courant algebroid
data that could provide a consistent world-sheet approach to realizing new
geometries appearing in string theory.  We  show that at the level of
the world-sheet sigma model action one is naturally lead to an  
apparent doubling of
degrees of freedom by careful analysis of equation of motion.
Furthermore, the bulk/boundary consistency condition provides a well-defined
procedure for obtaining the 2D reduced theory with background fluxes.  We
discuss some of the results from the perspective of  gauged sigma model.
