Abstract

We give the general solution for the elementary and solitonic D-brane configurations as a result of a reinterpretation of the already known p-branes. These solutions are found by means of a relevant conformal transformation on the string inspired action and its dual form. From this point of view, the nature of the electric and magnetic charge is clearer and the elementary and solitonic behaviour dependence on the initial lagrangian set. We give a complete characterisation of the spacetime defined by these solutions. The dual pair of instanton and 7-brane solution is presented as an example.
