On αψ –Compact Spaces
The objective of this paper is to obtain the properties of αψcompact spaces by using nets, filterbase, αψ-complete accumulation points and so on. We also investigate some properties of αψ-continuous multifunctions and αψ-compact spaces in the context of multifunction.
متن کاملOn function spaces of Corson-compact spaces
We apply elementary substructures to characterize the space Cp(X) for Corsoncompact spaces. As a result, we prove that a compact space X is Corson-compact, if Cp(X) can be represented as a continuous image of a closed subspace of (Lτ ) × Z, where Z is compact and Lτ denotes the canonical Lindelöf space of cardinality τ with one non-isolated point. This answers a question of Archangelskij [2].
متن کاملHorizontal Heegaard Splittings of Seifert Fibered Spaces
We show that if an orientable Seifert fibered space M with an orientable genus g base space admits a strongly irreducible horizontal Heegaard splitting then there is a one-to-one correspondence between isotopy classes of strongly irreducible horizontal Heegaard splittings and elements of Z. The correspondence is determined by the slopes of intersection of each Heegaard splitting with a collecti...
متن کاملPositive Diagrams for Seifert Fibered Spaces
obtained by adding 2-handles to S× [−1, 1] along the curves of X×−1 and Y ×1 and then adding 3-handles along all resulting 2-sphere boundary components. The decomposition of M by S × 0 is the associated (Heegaard) splitting of M and the genus of S is called the genus of the splitting. A positive diagram is a diagram in which S, X , and Y are oriented and the intersection number < X, Y >p of X w...
متن کاملModuli Spaces, Representable Functors, and Fibered Products
The idea of a moduli space is that its points correspond to a geometric object of interest. The underlying set of the space is thus determined, but not its geometric structure. In most cases, one can describe a geometric structure in an ad hoc manner, but it is not immediately obvious how to rigorously formulate the idea that the resulting object is “the” moduli space for the problem. This is t...
