| 描述 | ??????This book is devoted to fully developing and comparing?the two main approaches to the numerical approximation of controls for wave propagation phenomena: the continuous and the discrete.?This is accomplished?in the abstract functional setting of conservative semigroups.The main results of the work unify, to a large extent, these two?approaches, which yield?similaralgorithms and convergence rates. The discrete approach, however, gives?not only efficient numerical approximations of the continuous controls, but also ensures some partial controllability properties?of the finite-dimensional approximated dynamics. Moreover, it has?the?advantage of leading to iterative approximation processes that converge without a limiting threshold in the number of iterations. Such a threshold, which is hard to compute and estimate in practice, is a drawback of the methods emanating from the continuous approach.?To complement this theory, the book provides convergence results for the discrete wave equation when discretized using finite differences and proves the convergence of the discrete wave equation with non-homogeneous Dirichlet conditions. The first book to explore these topics in depth, "O |
