Following hep-th/0305177, we write the boundary state of half S-brane inbosonic string theory as a grand canonical partition function of a unitarymatrix model. From this representation, it follows that the annulus amplitudecan be written as a grand canonical partition function of a unitary two-matrixmodel. We also show that the contribution of the exponentially growingcouplings to the timelike oscillators can be resummed in a certain annulusamplitude.Comment: 27 pages, lanlmac; v2: reference adde
