Approximating Sequences and Bidual Projections
SINCE the appearance of Enflo's negative solution to the approximation problem [3], only a few positive general results on the approximation properties have been obtained. However, it is shown in [2] that any separable Banach space with the metric approximation property (M.A.P.) has the commuting metric approximation property. More precisely, if X has (MAP) there exists a sequence {Rn} of finit...
متن کاملBidual Horn Functions and Extensions
Partially defined Boolean functions (pdBf) , where are disjoint sets of true and false vectors, generalize total Boolean functions by allowing that the function values on some input vectors are unknown. The main issue with pdBfs is the extension problem, which is deciding, given a pdBf, whether it is interpolated by a function from a given class of total Boolean functions, and computing a formu...
متن کاملMaximal monotone operators with a unique extension to the bidual
We present a new sufficient condition under which a maximal monotone operator T : X ⇉ X∗ admits a unique maximal monotone extension to the bidual T̃ : X∗∗ ⇉ X∗. For non-linear operators this condition is equivalent to uniqueness of the extension. The class of maximal monotone operators which satisfy this new condition includes class of Gossez type D maximal monotone operators, previously defined...

15 صفحه اولGraph Matrix Completion in Presence of Outliers
Matrix completion problem has gathered a lot of attention in recent years. In the matrix completion problem, the goal is to recover a low-rank matrix from a subset of its entries. The graph matrix completion was introduced based on the fact that the relation between rows (or columns) of a matrix can be modeled as a graph structure. The graph matrix completion problem is formulated by adding the...
