Mathematical Analysis of the Problems faced by the People With Disabilities (PWDs)
In this direction the best results that exist were proved by Tjuriemskih and Nikolskii [10, 11] and state that a suffi cient condition for the validity of such a lethargy theorem is that X = H is a Hilbert space and that a necessary condition is that X = X ∗∗ (i.e., X must be a reflexive space), respectively.
Characterization of approximation schemes satisfying Shapiro's Theorem
Another focus for a generalization of the lethargy theorem that has been deeply studied is to maintain the finite -dimensional chains of subspaces of X but looking for more general spaces X than those given by the Banach setting, where a distance function is well defined and a Lethargy theorem holds true.
