The Quasi-Cauchy Relation and Diagonal Updating
The quasi-Cauchy (QC) relation is the weak quasi-Newton relation of Dennis and Wolkowicz [SIAM J. Numer. Anal., 30 (1993), pp. 1291–1314] with the added restriction that full matrices are replaced by diagonal matrices. This relation is justified and explored and, in particular, two basic variational techniques for updating diagonal matrices that satisfy it are formulated. For purposes of illust...
متن کاملCharacterizations of weak Cauchy sn - symmetric spaces
This paper proves that a space X is a weak Cauchy sn-symmetric space iff it is a sequentially-quotient, π-image of a metric space, which answers a question posed by Z. Li. 2000 Mathematics Subject Classification: 54C05, 54C10, 54E40.
متن کاملMore about Spaces with a Small Diagonal
Hušek defines a space X to have a small diagonal if each uncountable subset of X disjoint from the diagonal, has an uncountable subset whose closure is disjoint from the diagonal. Hušek proved that a compact space of weight ω1 which has a small diagonal, will be metrizable, but it remains an open problem to determine if the weight restriction is necessary. It has been shown to be consistent tha...
