Web07. jul 2024. · There are plenty of non-paracompact manifolds we could take as examples, the simplest one is of course the long line $\mathbb{L}$, which is roughly obtained by taking $\omega_1$ (the first uncountable ordinal) copies of $[0, 1)$, put the basic lexicographic topology to order it, and mirroring it around zero. Webnormal and [hereditarily] countably paracompact. Among the problems left unsolved and discussed at the end is the ambious question of whether it is consistent that hereditarily ...

WebLOCALLY COMPACT, HEREDITARILY NORMAL SPACES Paul Larson1 and Franklin D. Tall2 November 29, 2010 Abstract. We establish that if it is consistent that there is a supercom-pact cardinal, then it is consistent that every locally compact, hereditarily normal space which does not include a perfect pre-image of ! 1 is heredi-tarily paracompact.

Web15. mar 2024. · Theorem 1. Let X be a paracompact p -space, and let {\cal F} be a normal functor of degree \geqslant 3 acting in the category {\cal P} . Then, if the space {\cal F} (X) is hereditarily normal, then X is a metrizable space. The category Comp of compacta and their continuous mappings is the subcategory of {\cal P} , the restriction of a normal ...
