We also give a model where the oppositefeature occurs: instead of favouring the concentrationof transport rays, the variationalfunctional prevents it giving a lower cost todiffused measures.The mathematical model will be consideredin an abstract metric space frameworkwhere both behaviours (favouring concentrationand diffusion) are included; we donot know of natural phenomena where thediffusive behaviour occurs.The results presented here are contained inA.
