On the Dimension of Almost Hilbertian Subspaces of Quotient Spaces
The question of the dimension of almost Hilbertian subspaces is resolved in [1] where it is shown that every Banach space E of dimension n possesses almost Hilbertian subspaces of dimension c(logn), where c is an absolute constant, and that this estimate is the best possible. When the net is spread wider to include quotient spaces and subspaces of quotient spaces we should expect to find instan...
متن کاملCentral and Almost Constrained Subspaces of Banach Spaces
In this paper we continue the study of central subspaces initiated in [2] and its infinite version called almost constrained subspaces. We are interested in studying situations where these intersection properties of balls lead to the existence of a linear projection of norm one. We show that every finite dimensional subspace is a central subspace only in Hilbert spaces. By considering direct su...
متن کاملSubspaces of Knot Spaces
The inclusion of the space of all knots of a prescribed writhe in a particular isotopy class into the space of all knots in that isotopy class is a weak homotopy equivalence.
متن کاملSubspaces of pseudoradial spaces
We prove that every topological space (T0-space, T1-space) can be embedded in a pseudoradial space (in a pseudoradial T0-space, T1-space). This answers the Problem 3 in [2]. We describe the smallest coreflective subcategory A of Top such that the hereditary coreflective hull of A is the whole category Top.
متن کاملThe Daugavet equation for operators on function spaces
We prove the norm identity ‖Id + T ‖ = 1 + ‖T ‖, which is known as the Daugavet equation, for weakly compact operators T on natural function spaces such as function algebras and L-predual spaces, provided a non-discreteness assumption is met. We also consider c0-factorable operators and operators on CΛ-spaces.
