### Abstract

We investigate the relation between the general solution with the symmetry SO(p) × SO(9 - p) of Type II supergravity (the four-parameter solution) and the boundary states which hold the same symmetry. This solution has a horizon in some parameter regions, different from the SO(l,p) × SO(9 - p)-symmetric solution which had been investigated in our previous works [1, 2]. We studied when the solution has a horizon and what kind of the boundary states can reproduce the asymptotic behavior of the solution, which might be useful to interpret the horizons of black holes in the general relativity in terms of the string theory.
