Dipartimento di matematica3 aWe investigate Mori dream spaces obtained by blowing-up the n-dimensional
complex projective space at n+1, n+2 or n+3 points in very
general position. Using toric techniques we study the movable cone of
the blow-up of Pn at n+1 points, its decomposition into nef chambers
and the action of theWeyl group on the set of chambers. Moreover, using
different methods, we explicitly write down the equations of the movable
cone also for Pn blown-up at n+2 points.10aMori dream space1 aLo Giudice, Alessio1 aCacciola, Salvatore1 aDonten-Bury, M.1 aDumitrescu, O.1 aPark, J. uhttp://hdl.handle.net/1963/6613
