Bosonic string theories with new boundary conditions

  • S M Roy

We show that the classical Nambu-Goto string inD dimensions admits Poincaré invariance ind dimensions (dD) if (i)d − 2 of the transverse co-ordinatesx i are periodic and the rest quasi-periodic involving a real orthogonal matrix with (D − d) (D − d − 1)/2 free parameters, or if (ii)d − 2 ofx i obey Neumann and the rest obey a boundary condition involvingN free parameters, whereN=(D − d)2/2 ifD − d is even, andN=[(D − d)2 − 1]/2 ifD − d is odd.
