Intergenerational equity: sup, inf, lim sup, and lim inf

We study the problem of intergenerational equity for utility streams and a countable set of agents. A numerical social welfare function is invariant to ordinal transformation, satis…es a weak monotonicity condition, and an invariance with respect to concatenation of utility streams if and only if it is either the sup, inf, lim sup, or lim inf.

Inf-sup conditions for twofold saddle point problems

Necessary and sufficient conditions for existence and uniqueness of solutions are developed for twofold saddle point problems which arise in mixed formulations of problems in continuum mechanics. This work extends the classical saddle point theory to accommodate nonlinear constitutive relations and the twofold saddle structure. Application to problems in incompressible fluid mechanics employing...

On inf-sup stabilized finite element methods for transient problems

We consider the behavior of inf-sup stabilization in the context of transient problems with multiple time scales. Our motivation for studying this setting is provided by reacting flows problems for which small time steps are necessary in the integration process. We show that for algorithms defined through a process wherein spatial and temporal discretizations are separated, the coupling of impl...

Inf-sup Conditions

where u can be interpreted as the velocity field of an incompressible fluid motion, and p is then the associated pressure, the constant μ is the viscosity coefficient of the fluid. For simplicity, we consider homogenous Dirichlet boundary condition for the velocity, i.e. u|∂Ω = 0 and μ = 1. The conditions for the well posedness is known as inf-sup condition or Ladyzhenskaya-Babuška-Breezi (LBB)...

Inf-Sup stability of the discrete duality finite volume method for the 2D Stokes problem

“Discrete Duality Finite Volume” schemes (DDFV for short) on general 2D meshes, in particular non conforming ones, are studied for the Stokes problem with Dirichlet boundary conditions. The DDFV method belongs to the class of staggered schemes since the components of the velocity and the pressure are approximated on different meshes. In this paper, we investigate from a numerical and theoretica...
