This paper contains two main contributions. First, it provides optimal stability estimates for advection-diffusion equations in a setting which the velocity field is Sobolev regular spatial variable. estimate formulated with help of Kantorovich--Rubinstein distances logarithmic cost functions. Second, are extended to fields whose gradients singular integrals $L^1$ functions entailing new well-p...

This note reconsiders the Rubinstein bargaining game under assumption that a rejected offer is only costly to proposer who made offer. It shown then, classic result of Shaked that, in multilateral version this game, every division good can be sustained SPE no longer holds. Specifically, there are many SPE, but players’ (expected) payoffs unique. The further leads responder advantage.
