STRONG DUALITY FOR GEOMETRIC OPTIMIZATION AND L_P-NORM OPTIMIZATION USING A CONIC FORMULATION Geometric optimization can be cast as a convex problem with an interesting strong duality property : the optimum duality gap is equal to zero. l_p-norm optimization problems also share this property, with the addition that their dual optimum objective value is attained at a feasible solution. In this talk, we formulate these problems as primal-dual pairs using dedicated convex cones, which allow us to derive these strong duality properties rather easily.
