Fast energy decay for wave equations with a localized damping in the n-dimensional half space
Prof. Ryo Ikehata
Universidade de Hiroshima, Japão
We consider a mixed problem for wave equations with a localized damping near spatial infinity in the n-dimensional half space. By constructing a new type of Hardy inequality in the whole space via the Fourier transform, we will derive a fast decay rate of the energy to the odd extension of the corresponding solution. In this case we employ a special type of multiplier method combined with the Hardy type inequality.

Inexact Dual Dynamic Programming
Vincent Guigues (EMAp/FGV-Rio)
Resumo: We introduce an extension of the Dual Dynamic Programming method to solve convex optimization problems.
We call Inexact DDP (IDDP) this extension which applies to situations where all primal and dual subproblems are solved with a bounded error. We also study the convergence of this inexact variant of DDP.
As a by-product, our analysis provides descriptions of the epsilon-subdifferential of the value function of a convex problem when the corresponding primal and dual problems are solved approximately.
The algorithm and convergence analysis can be extended to the stochastic case.
