Supersymmetric D0-branes in curved backgrounds

An action for supersymmetric D0-branes in curved backgrounds is obtained by dimensional reduction of N=1 ten-dimensional supergravity coupled to super Yang-Mills system to 0+1 dimensions. The resultant action exhibits the coset-space symmetry SO(9,9+n)SO(9)×SO(9+n)×U(1) where n=N2−1 is the dimension of the SU(N) gauge group.
