Weak Regularity of Gauss Mass Transport
نویسنده
چکیده
Given two probability measures μ and ν we consider a mass transportation mapping T satisfying 1) T sends μ to ν, 2) T has the form T = φ ∇φ |∇φ| , where φ is a function with convex sublevel sets. We prove a change of variables formula for T . We also establish some a priori estimates for T , and a new form of the parabolic maximum principle. In addition, we discuss relations to the Monge–Kantorovich problem, curvature flows theory, and parabolic nonlinear PDE’s.

Strong Topological Regularity and Weak Regularity of Banach Algebras
In this article we study two different generalizations of von Neumann regularity, namely strong topological regularity and weak regularity, in the Banach algebra context. We show that both are hereditary properties and under certain assumptions, weak regularity implies strong topological regularity. Then we consider strong topological regularity of certain concrete algebras. Moreover we obtain ...
متن کاملArens Regularity and Weak Amenability of Certain Matrix Algebras
Motivated by an Arens regularity problem, we introduce the concepts of matrix Banach space and matrix Banach algebra. The notion of matrix normed space in the sense of Ruan is a special case of our matrix normed system. A matrix Banach algebra is a matrix Banach space with a completely contractive multiplication. We study the structure of matrix Banach spaces and matrix Banach algebras. Then we...
متن کاملThe optimal partial transport problem
Given two densities f and g, we consider the problem of transporting a fraction m ∈ [0, min{‖f‖L1 , ‖g‖L1}] of the mass of f onto g minimizing a transportation cost. If the cost per unit of mass is given by |x − y|2, we will see that uniqueness of solutions holds for m ∈ [‖f ∧ g‖L1 , min{‖f‖L1 , ‖g‖L1}]. This extends the result of Caffarelli and McCann in [8], where the authors consider two den...
متن کاملGlobal weak solutions and asymptotic limits of a Cahn--Hilliard--Darcy system modelling tumour growth
We study the existence of weak solutions to a Cahn–Hilliard–Darcy system coupled with a convection-reaction-diffusion equation through the fluxes, through the source terms and in Darcy’s law. The system of equations arises from a mixture model for tumour growth accounting for transport mechanisms such as chemotaxis and active transport. We prove, via a Galerkin approximation, the existence of g...
متن کاملA Gauss-Newton method for convex composite optimization
An extension of the Gauss{Newton method for nonlinear equations to convex composite optimization is described and analyzed. Local quadratic convergence is established for the minimization of h F under two conditions, namely h has a set of weak sharp minima, C, and there is a regular point of the inclusion F(x) 2 C. This result extends a similar convergence result due to Womersley which employs ...
