We calculate interaction between two separated spherical D2 branes in bosonic string theory (SU(2)WZW model). Geometrical configuration is following. Target space is three sphere and D2 branes are 2-spheres which do not have to be co-centric. Three arbitrary parameters are introduced; radius of sphere andﾊ distance between centers of spheres. We explain how to defineﾊ boundary condition and boundary state depending on these parameters. Then we calculate partition function as a overlap of boundary state. In order to check calculation we reproduce partition function of 0-branes in flat three dimensional space. This calculation probably corresponds that of two fuzzy sphere configuration in a matrix model with an additional term though, it is not yet done however. |
