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.
متن کاملInf-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)...
متن کاملOn 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...
متن کاملInf-Sup Control of Discontinuous PWA Systems
Piecewise affine (PWA) systems is an important class of systems. In this paper we consider optimal control of constrained, discontinuous, discrete-time, piecewise affine systems with state and input dependent disturbances. We seek to pre-compute, via dynamic programming, an explicit control law for these systems when a piecewise affine cost function is utilized. The main difficulty with this pr...
متن کاملContinuity Properties of the Inf-Sup Constant for the Divergence
The inf-sup constant for the divergence, or LBB constant, is explicitly known for only few domains. For other domains, upper and lower estimates are known. If more precise values are required, one can try to compute a numerical approximation. This involves, in general, approximation of the domain and then the computation of a discrete LBB constant that can be obtained from the numerical solutio...
